Modern Forage: How This Works
Modern Forage catalogs American dishes that are common knowledge inside one metro and a blank stare two hundred miles away. This post is the methodology: the four-factor inclusion test, the exclusion categories, the source threshold, the disposition rubric, the four ways a dish gets locked in, and the geographic ladder from hyperlocal to regional. Treat it as the reference for everything else in the series.
Modern Forage is a survey of American dishes that have stayed put. The kind of food that locals in one metro know by name and most people two hundred miles away have never heard of. Goetta in Cincinnati, the Springfield horseshoe, chislic on a South Dakota bar menu, the Cincinnati steak hoagie that’s standard at Cincinnati pizzerias and largely absent from Philadelphia ones. The survey is the inventory of these dishes. This post is the criteria.
The motivating idea is that American regional food has two cohorts. The famous one (deep-dish pizza, the Philly cheesesteak, lobster rolls, Nashville hot chicken, the Reuben) has escaped to airport menus and national chains and food TV. The other cohort has not, or not to anything like the same degree. Most of those dishes have a documented immigrant lineage, a defining neighborhood, a lunch counter or butcher shop where a generation of locals first encountered them. They show up on many menus inside a single metro and rarely on menus a state away. They are the survey’s subject.
The line between the two cohorts is not always clean. Some dishes have escaped the dish but not the practice (Flaming Saganaki). Some live in two unrelated places without crossing into national food consciousness (Walker Bros Apple Pancake). Some have multi-vendor presence inside a single metro and almost no media coverage outside it (the Beef Roll). The criteria below name those edge cases explicitly so the reader can see roughly where the line falls and why.
The four-factor test
A dish qualifies for the survey if it meets at least two of four factors. Two is the floor, not the target. Most promoted entries hit three or four. A dish that meets only one of these factors does not qualify. A dish that meets all four is canonical.
Geographic containment (the weakest factor)
This is the weakest of the four factors and the one applied with the most judgment. The cleanest formulation is that the dish is concentrated in a specific region and has not entered national or international consciousness. Earlier framings used a rough hundred-to-two-hundred-mile rule of thumb, and that still describes the cleanest hyperlocal entries (a goetta or a cheese crown that essentially doesn’t appear at retail outside the Cincinnati MSA). But good dishes travel. Sometimes they spread through diaspora restaurants in a transplant city, sometimes through a mid-size regional chain, sometimes through a slow diffusion across an immigrant-belt corridor that crosses several state lines. The Cornish pasty has concentrations in Michigan’s Upper Peninsula, Butte Montana, Grass Valley California, and other mining-immigrant towns: mileage-wise the corridor is huge, but consciousness-wise the dish is largely invisible to American eaters outside those communities. The Beef Roll spans the Illinois Valley but has nearly zero national food-media footprint. The working test is concentration plus low visibility outside the home region, not raw distance from a single origin point. Even then, plenty of close calls survive on judgment alone. The survey is curated by a human and there is irreducible subjectivity about which traveled-but-still-niche dishes count and which don’t. Most of the time, dishes that have spread within a coherent region or to a few disparate diaspora cities are still counted in. The line is real but it is not crisp.
Name-recognition failure
Ordering the dish outside its home metro produces a blank stare. The “blank stare two hundred miles away” test is the colloquial form. This is the factor most commonly surfaced by diaspora-signal Reddit comments shaped like “I moved from X and can’t find Y anywhere.” The shock of an outsider discovering the dish is local is itself one of the strongest qualitative signals the survey records.
No national chain adoption
The dish has not been picked up by national franchises. McDonald’s, Olive Garden, Domino’s, and Applebee’s have not added it to their menus. A dish that Domino’s only serves in a few specific ZIP codes (the Cincinnati steak hoagie pattern) qualifies on this factor; a dish that Domino’s serves nationwide does not. National chain modification of menus for a single metro is a textbook containment signal in the other direction.
Active local culture
The dish is currently eaten by locals, not preserved as a museum piece for tourists. There is at least one active vendor selling it daily, ideally several. A century-old dish whose only remaining home is a single annual festival qualifies marginally on this factor; a dish on the everyday menu at a chain of multi-location butcher counters qualifies strongly.
What gets excluded
Six categories of dish or near-dish are excluded on principle. They get sorted and noted, not relitigated. The exclusion list is the most common answer to the reader question “why isn’t my favorite local food in the survey,” so it earns top billing here.
Nationally famous regional icons. Once a dish is on airport menus, in national chain rotation, on Food Network, or in airport gift-shop souvenirs, it has escaped. The point of the survey is what hasn’t.
Single restaurants that locals love but that don’t represent a regional tradition. A diner that has carved out a beloved local SKU is not the same thing as a city-wide foodway. The James Beard Foundation’s “America’s Classics” award honors restaurants, not dishes; an America’s Classics winner does not, by itself, indicate a survey-eligible dish.
Ingredients masquerading as dishes. A regional fruit (paw paw, Montana huckleberry) or a regional condiment is not a dish in the survey’s sense. Ingredients and condiments live in the survey’s regional condiments and regional snacks tracks, not in the main dish catalog.
Formats masquerading as dishes. The Hawaiian plate lunch, the Vegas casino buffet, “school lunch culture,” the Wisconsin supper club: each is a dining structure that hosts many dishes, not a dish itself. Components of these formats can qualify on their own (the Wisconsin Friday fish fry); the format does not.
Immigrant ecosystems rather than immigrant adaptations. LA’s Koreatown serves authentic Korean food at high quality and high density; that’s an ecosystem of imported tradition, not a hyper-local American invention. Stockton’s Filipino food scene is similarly an immigrant ecosystem rather than an adapted-for-local-palate dish family. The survey is interested in the adaptation, not the import.
Brands standing in for dishes. Vernors ginger soda, Cheerwine, Grippo’s chips, Old Vienna Red Hot Riplets: these are regional brands with strong local identity, but a brand is not a dish. They appear in the regional snacks and regional condiments tracks. Lookup-by-brand belongs in those catalogs.
Contested-origin dishes
When a dish has multiple cities making competing origin claims (the chimichanga’s Tucson-versus-Yuma-versus-Mexico dispute is the standard example), the survey includes the dish in each claimant’s locale post with an explicit note about the contested attribution. Treating contested origin as a disqualifier would lose too many genuinely regional dishes, since origin disputes often track real parallel invention or convergent evolution within an immigrant community spread across multiple cities. The survey’s premise is regional containment, not single-origin certainty. A dish that’s contested between Tucson and Yuma is still hyper-local to the southern Arizona / northern Sonora corridor; both Tucson and Yuma posts can reasonably claim it as long as each notes the dispute.
The source threshold
Beyond the four-factor test, every entry needs independent named sources. The minimum for inclusion at all is two named sources. The target for a confident promotion is five to eight.
A “named source” is food media (Atlas Obscura, Eater, Saveur, Cooking Light), local TV news (Cincinnati’s WCPO and WLWT, St. Louis’s KSDK), longform journalism (CityBeat, Cincinnati Magazine, Texas Monthly), academic press (university food studies, regional cookbook scholarship), oral histories captured in print or podcast, and food-historian blogs with traceable citations (Dann Woellert in Cincinnati, John T. Edge in the South). It is not Reddit, single Yelp reviews, or marketing copy from the vendor’s own site.
Reddit threads are explicitly seed signals, not sources. They generate candidates and surface the diaspora-signal “can’t find it anywhere” pattern that points the survey at things to research. The actual case for inclusion has to be built from named sources independent of the seed.
A dish that has only one or two named sources is deferred, not promoted. Deferral is not exclusion: it is a holding pattern with an explicit unlock condition recorded in the research tracker. “Promote when a longform piece appears” or “promote when the diaspora signal can be traced to specific transplant communities” or “promote when the immigrant-community lineage is documented in a cookbook.” The deferred list is the working agenda.
Allowed partial-containment readings at the edges
The survey accepts three patterns that don’t strictly satisfy all four factors but that are structurally interesting enough to include with explicit framing.
A few places, no national attention. A dish that lives in a small set of unrelated homes (often the original plus a transplant or franchise lineage) without crossing into national food consciousness. Walker Bros Apple Pancake (Portland-chain origin, Chicago’s North Shore home, neither version reaching national food media in any meaningful way) qualifies under this reading despite having more than one legitimate home.
Practice-locked but dish-traveled. The dish has escaped the metro but the preparation routine, the service ritual, or the scene around it is still strongly identified with one place. Flaming Saganaki has migrated to Greek restaurants nationwide; the tableside flame and the “Opa!” theater are most strongly identified with Chicago Greektown, where the form was popularized in the late 1960s. These entries get included with an explicit caveat blockquote noting what has traveled and what has not.
Total media invisibility plus broad local presence. A dish that appears on many menus inside a single metro yet has nearly no coverage in Wikipedia, no NYT mention, no LTHForum thread, and no Eater write-up. Broad local saturation paired with near-total outsider silence is itself one of the strongest containment signals the survey records. The Beef Roll is the canonical example: many Illinois Valley menus, a near-complete absence in national food media.
How candidates get classified
Every candidate that surfaces (from a Reddit thread, a diaspora email, a personal trip) gets exactly one of these classifications, with the reason recorded in the research tracker.
PROMOTE. Meets two or more of the four factors, has five or more named sources, has multi-vendor presence (or single-vendor with an explicit structural lock), and has either documented diaspora signal or strong containment evidence. Goes into the canonical survey and a city blog post.
PROMOTE WITH CONTAINMENT CAVEAT. Structurally interesting but the dish has escaped the metro under one of the three partial-containment readings above. Goes in with the caveat as marginalia and a blockquote in the entry body.
DEFER. Promising but under-sourced (one or two named sources, not yet five). The tracker records the specific unlock condition: what additional research mechanism would promote this. Cookbook mining, a focused diaspora thread, an oral history. Deferral is a holding pattern, not a no.
EXCLUDE. Falls into one of the disqualifying categories above. The exclusion reason is recorded explicitly so the survey doesn’t relitigate the same candidate every time it gets suggested.
ALREADY COVERED. Already in the canonical survey or a published blog post. Recorded with the file and section pointer so the reference is fast.
PROMOTION CANDIDATE. Currently city-locked in the canonical survey, but a new thread or independent research surfaces the same dish in an adjacent metro. Triggers a re-framing of the existing entry rather than a new one.
Four ways a dish gets locked in
Each promoted entry names the mechanism that keeps the dish geographically contained. There are four primary categories, drawn from the entries already in the survey.
Immigrant-community-locked
The most common mechanism in the survey. A dish that arrived with a specific immigrant community, embedded in their neighborhood institutions (butcher shops, bakeries, parish festivals, social clubs), and didn’t find a propagation channel outside that community. The Cornish mining corridor’s pasty distribution across Michigan’s Upper Peninsula, Butte Montana, Grass Valley California, and other 19th-century mining towns. The German-Russian Great Plains belt across North and South Dakota and Nebraska. Greek immigrants who turned American Coney Island chains into a dish family (Detroit Coney Dog). Cantonese restaurateurs who invented dishes for the local Anglo-American palate (Springfield-style cashew chicken, the Detroit almond boneless chicken, the St. Paul sandwich).
Apparatus-locked
A dish that requires a specific piece of equipment that has barely propagated outside the home region. Chicago’s aquarium smokers for rib tips and hot links. Provel cheese, a process cheese produced primarily for the St. Louis pizza market. The Ball Cream Beater that anchors the Cincinnati opera cream tradition. The dish travels roughly as far as the apparatus does.
Operational-routine-locked
A dish that depends on a specific service routine that resists migration. The canonical example, and the thinnest mechanism category in the survey, is Chicago Pizza and Oven Grinder Co.’s Pizza Pot Pie in Lincoln Park: a triple-raised Sicilian dough is draped over an inverted ceramic bowl of toppings, baked upside-down so the dough forms a domed lid, then carried to the table and flipped to plate. The dough has to triple-raise or it won’t form the dome; the bowl has to be the right shape or the inversion fails. The recipe has not changed since 1972 and the restaurant has never licensed or franchised it. Cincinnati chili’s “Way” ordering language (3-Way, 4-Way, 5-Way) is a softer multi-vendor variant of the same idea: the service convention is preserved across Skyline, Gold Star, Camp Washington, and Empress even when individual cooks vary the recipe. Most candidates that look operational-routine-locked turn out to be recipe-locked or apparatus-locked once you push on them.
Commitment-purchase-locked
A dish that sells primarily in formats few outsiders would buy on impulse. The Atomic Cake (sold as whole cakes, not by the slice, per the Chicago bakeries that make it). The Pittsburgh Cookie Table (a wedding tradition built on dozens of homemade cookie varieties contributed by extended family). The dish rarely reaches the casual passing customer because it does not come in a casual format.
A few entries layer mechanisms. The cheese crown is immigrant-community-locked (Cincinnati’s German-American bakery network) and apparatus-adjacent (the muffin-tin baking form that defines the cup-and-crown shape). Some entries land in a fifth informal category that has not been formalized: tribute-product-locked, where the dish itself is so embedded that local non-dish brands (Northside’s Fish Logs Cider and Fish Logs gelato; Graeter’s Cheese Crown ice cream) reproduce it in adjacent product categories. The tribute pattern is a load-bearing cultural-lock signal even when the dish itself has only one or two active vendors.
Geographic scale
The survey uses a three-rung ladder for how broadly a dish has spread.
Hyperlocal entries are locked to a single neighborhood, a single shop, or a single immigrant enclave. The Old Timber Inn fish log in Cincinnati’s Northside (originator), Lake Nina (active torchbearer), one or two tribute brands. Walker Bros Apple Pancake at a small set of Chicago’s North Shore locations.
City-wide entries cross the metro: multiple vendors in multiple neighborhoods. Goetta. The Cincinnati steak hoagie. The Detroit Coney Dog. The Springfield horseshoe.
Regional entries cross adjacent metros within a coherent geography. The Upper Peninsula Pasty across Marquette, Houghton, and Iron Mountain. The Beef Roll across the Illinois Valley from LaSalle through Peru, Ottawa, and Mendota. City Chicken across the Polish-and-Italian-immigrant Great Lakes belt from Pittsburgh through Cleveland to Detroit, Buffalo, Binghamton, and (recently confirmed) Cincinnati.
A hyperlocal entry can be promoted to regional when independent threads or research surface the same dish across adjacent metros. Promotion is the right move when the diffusion was always there but the original survey only had visibility on one node of it.
How to contribute
The survey lives in the open at subprojects/modern_forage on GitHub. The dishes catalog, the research tracker (including the deferred and excluded lists with reasons), the named geographic regions, and the per-Reddit-thread research logs are all there.
Modern Forage runs primarily on diaspora signal: the “I moved from X and can’t find Y anywhere” comment is the highest-leverage input the survey accepts. Suggestions are welcome at u/strcrssd on Reddit or as GitHub issues against the repo. The fastest path from suggestion to published entry is a comment with a named source attached.
The survey is incomplete and will stay that way. New entries surface monthly. Existing entries get re-categorized when adjacent-metro research extends their geography. Excluded entries occasionally get re-evaluated when new evidence arrives. The published posts are snapshots; the canonical survey at GitHub is the moving target.
