Food and Drink Atlas
Things this atlas does not know. Each entry is a question that specialists
have posed and not settled, recorded with what would actually resolve it and which
expertise the answer needs.
These are kept deliberately, rather than quietly omitted. An atlas that shows
only what it is sure of implies a confidence it has not earned, and the gaps are often where
the interesting work is. Several sit exactly where two fields fail to meet: identifying the
hyssop of the Hebrew Bible needs a botanist and a philologist of Biblical Hebrew, and neither
one settles it alone.
Grouped by the field an answer needs. A question sitting between two disciplines appears under both, which is why the group counts add up to more than the number of questions.

Negroni
Was the Negroni actually invented by Count Camillo Negroni in Florence, or did it originate in 1920s France?
Open Negroni
Why It Is Open The popular legend credits Count Camillo Negroni in Florence, generally dated around 1919, but no contemporary documentation of that story has been found. The earliest secured print attestations of a matching 1:1:1 recipe are French cocktail books from the late 1920s, under different names (Campari Mixte, Camparinete), with the name Negroni only attached in the late 1940s.
What Would Settle It A verified pre-1929 print source connecting the Negroni family or the city of Florence to this exact drink, or, alternatively, an even earlier French or Italian source confirming the drink's presence before the 1929 Alimbau and Milhorat cocktail book.

Negroni (Wikipedia), Lead section.
Bubble Tea
Which Taiwanese tea room actually invented bubble tea first?
Open Bubble Tea
Why It Is Open The Hanlin Tea Room in Tainan claims to have invented bubble tea in 1986; the Chun Shui Tang tea room in Taichung credits product-development staffer Lin Hsiu Hui with the idea in 1988. The two shops litigated the question for roughly a decade, and a 2019 Taiwanese court ruling declined to assign credit to either side, holding the drink an unpatentable general food product.
What Would Settle It A contemporaneous document, receipt, menu or press account from 1986 to 1988 naming tapioca-ball tea at one shop earlier than the other.

Bubble Tea (Wikipedia), Lead section.
Mead
How far back does mead-making actually extend, and did it arise once or independently in multiple regions?
Open Mead
Why It Is Open Naturally fermented honey and water is easy to produce by accident, so mead may have been discovered independently by early humans in many places tens of thousands of years before written history. The earliest textual evidence (the Rigveda's soma, roughly 1700 to 1100 BCE) and the earliest strong archaeological evidence (pottery residue from northern China, at least 7000 BCE) are geographically and chronologically unconnected, and neither can be treated as the drink's true point of origin.
What Would Settle It Archaeological residue evidence, securely dated and geographically mapped, sufficient to distinguish a single point of origin from independent, unconnected invention in more than one region.
Expertise Needed Archaeology and archaeometry of fermented beverages
Question posed in
Mead (Wikipedia), Lead section.
Cashew
When was the cashew first used by its Indigenous South American originators?
Open Cashew
Why It Is Open The source documents only the 16th-century Portuguese contact and spread of the cashew, a European-contact date, not an Indigenous first-use or domestication date; no earlier archaeological or textual attestation was found.
What Would Settle It Archaeobotanical remains of Anacardium occidentale from a pre-Columbian Brazilian site, dated and published.
Question posed in
Cashew (Wikipedia), Lead section.
Maple Syrup Production
When did Indigenous peoples of Northeastern North America first begin making maple syrup?
Open Maple Syrup Production
Why It Is Open Every source consulted (Wikipedia's Maple syrup article, the National Museum of the American Indian's own magazine) agrees the practice is ancient and predates European contact by a long span, and Wikipedia states plainly that there are no authenticated accounts of how maple syrup production and consumption began. The earliest fixable date found, 1680, marks European settlers and fur traders already harvesting maple products, a continuation of an established Indigenous practice, not its origin.
What Would Settle It An archaeological find (a boiling site, a processing vessel) or a dated Indigenous oral history account placing maple sap processing at a specific century before European contact.
Expertise Needed Food history and archaeology
Question posed in
Maple syrup (Wikipedia), History section, European adoption passage.
Boodle Fight
When did the Armed Forces of the Philippines' boodle fight tradition begin among Philippine Military Academy cadets?
Open Boodle Fight
Why It Is Open Wikipedia's Kamayan article describes the boodle fight as a tradition of the Armed Forces of the Philippines, originally practiced by Philippine Military Academy cadets and named for military slang from the United States Military Academy West Point, but names no year, decade or bounding period for when PMA cadets began the practice. A search of further secondary accounts found the same description with no added date.
What Would Settle It A Philippine Military Academy institutional history, a military historian's account, or a dated news reference naming when cadets began this specific communal eating custom.
Expertise Needed Military and food history
Question posed in
Boodle fight (Wikipedia), Kamayan article, boodle fight passage.
Merienda
When did the merienda custom of a light afternoon meal begin in southern Europe, and when did it spread to the Americas and the Philippines?
Open Merienda
Why It Is Open Wikipedia's Merienda article documents the custom's geography and its name's spread across Spain, Portugal, Italy, the former Yugoslavia, France, Hispanic America, the Philippines, North Africa and Brazil, but gives no year, century or era for when the custom began or for when it reached the colonies. A secondary source (Spanish Sabores) states plainly that the origins of the custom are murky, with no more specific date offered there either.
What Would Settle It A documented reference in a historical Spanish, Portuguese or Italian text naming a period when the merienda custom is first attested, or a colonial-era record dating its export to the Americas or the Philippines.
Expertise Needed Food history
Question posed in
Merienda (Wikipedia), Lead section, geography and language spread.
Sobremesa
When did the Spanish custom of sobremesa, lingering at the table after a meal, begin?
Open Sobremesa
Why It Is Open Wikipedia's Sobremesa article and La Tienda's own culture page both describe sobremesa as a living Spanish table tradition tied to agrarian life and the siesta, but neither names a year, century or era for when the custom of remaining at the table began.
What Would Settle It A dated literary or historical reference (a period cookbook, a travel account, an academic food-history source) naming when Spanish sobremesa is first documented as a named custom.
Expertise Needed Food history
Question posed in
Sobremesa (Wikipedia), Lead section, opening sentence.
Injera
When did injera, the Ethiopian and Eritrean fermented teff flatbread, originate?
Open Injera
Why It Is Open Wikipedia states the origin of injera is unknown; a folklore account places invention around 100 BC and mitad griddles are known from archaeological sites around 600 AD, but both are described as unconfirmed.
What Would Settle It A dated archaeological find of fermented-teff residue or an injera-specific artifact tied stratigraphically to a site, or a written record older than the 19th-century sources currently known, naming injera or its precursor by name.
Expertise Needed food history, archaeology
Question posed in
Injera (Wikipedia), History.
Naan
When and where was naan bread first made?
Open Naan
Why It Is Open Naan is an ancient Persian flatbread; the word itself is generic Persian for bread. The only dated textual evidence in the source is the Indo-Persian Sufi poet Amir Khusrau's memoirs, written in India in the 1300s AD, which is an early attestation of naan being eaten in that region, not a record of when or where the bread itself was first made. No source found gives an actual invention date or place.
What Would Settle It A food-history or archaeological source establishing when leavened, oven-baked flatbread first appeared in Persia specifically (as opposed to the broader family of Middle Eastern and South Asian flatbreads), with a citable date or period.

Rogan Josh
What year marks the close of rogan josh's origin period as a distinct Kashmiri dish, after the Mughals brought the Persian original north in the 16th century?
Open Rogan Josh
Why It Is Open Wikipedia's Origin section documents rogan josh being brought to North India by the Mughals in the 16th century and becoming a staple of the Kashmiri wazwan, but narrates this as a continuing evolution (through a later British Indian restaurant form) with no year or reign given for when the dish's Kashmiri identity was established. No defensible closing year for the origin period was found in the source.
What Would Settle It A dated primary or secondary source (a Mughal-era or early colonial Kashmiri court or culinary record, or a peer-reviewed food-history study) naming when rogan josh became a recognized, named Kashmiri dish rather than an ongoing Persian import.
Expertise Needed Culinary history / South Asian history
Question posed in
Rogan Josh (Wikipedia), Origin section, first paragraph.
Baba Ghanoush
When and where did baba ghanoush, the Levantine roasted-eggplant dish, first take its current form?
Open Baba Ghanoush
Why It Is Open Wikipedia's own entry gives no dated origin claim for the dish itself; the only date in the article (1979) is Hans Wehr's dictionary entry for the WORD bābā ghanūj, not evidence of when the dish itself arose.
What Would Settle It A food-history source (e.g. Gil Marks or Charles Perry) dating the dish, as opposed to the term, to a specific period or century.
Expertise Needed food history
Question posed in
Baba Ghanoush (Wikipedia), Etymology section.
Pita
When did the steam-puffed, two-layer pocket form of pita bread first appear?
Open Pita
Why It Is Open Wikipedia's own History section states there is no record of the pocket pita in ancient texts or medieval Arab cookbooks and that food historians such as Charles Perry and Gil Marks consider it "likely a later development," with no period or century named.
What Would Settle It A food-history source naming the period or region where the steam-puffed pocket technique was first documented, as distinct from the much older prehistoric Near Eastern flatbread lineage.
Expertise Needed food history
Question posed in
Pita (Wikipedia), History section.
Chana Masala
When did chana masala emerge as a distinct dish on the Indian subcontinent?
Open Chana Masala
Why It Is Open Wikipedia's own entry names the dish's regional home (the Indian subcontinent, North Indian and Pakistani cuisine) but gives no date or period for its emergence anywhere in the article.
What Would Settle It A food-history source dating chana masala's emergence as a named dish, as distinct from the much older general history of chickpea cookery in South Asia.
Expertise Needed food history
Question posed in
Chana Masala (Wikipedia), Introduction.
Fattoush
When did fattoush take shape as the distinct dish known today, rather than the earlier bread salads it may descend from?
Open Fattoush
Why It Is Open Wikipedia's article on fattoush cites a 10th-century Arabic cookbook by Ibn Sayyar al-Warraq recording a vegetarian tharid dish reminiscent of fattoush, and a late 19th-century description by Orientalist Reinhart Dozy of a bread-based dish close to today's fattoush, with the English word fattoush first attested in 1955. No source in the article fixes when the tharid-descended bread salad became the specific dish known as fattoush, so origin-start-year and origin-end-year are left unfilled rather than guessed from the loosely related medieval precedent.
What Would Settle It A food-historical study tracing bread salads in the Levant from the medieval Arabic tharid tradition through to the first clearly identified fattoush recipes, with dated textual evidence in between the 10th and 20th centuries.
Expertise Needed food history
Question posed in
Fattoush (Wikipedia), History section: 10th-century Ibn Sayyar al-Warraq cookbook, late 19th-century Dozy description, 1955 English attestation.
Harira
In what period, and where exactly, did harira take shape as a distinct soup, given the dispute between a specifically Moroccan origin and a broader Andalusian or Maghrebi origin?
Open Harira
Why It Is Open Wikipedia's article on harira reports that food historian Gil Marks attributes its origin to Morocco, calling this claim compelling but debatable, while Algerie Poste and the Andalusi scholar Ibn Razin al-Tujibi identify harira as an authentic Maghreb dish of Andalusian origin. The article gives no date range that both accounts would support, so origin-start-year and origin-end-year are left unfilled rather than guessed from either side of the dispute.
What Would Settle It A scholarly resolution of the competing Moroccan and Andalusian origin claims for harira, anchored to a specific dated text or archaeological finding rather than a named scholar's attribution alone.
Expertise Needed food history
Question posed in
Harira (Wikipedia), Origin section: Gil Marks Morocco attribution and Ibn Razin al-Tujibi Andalusian attribution.
Cassoulet
When did the dish now called cassoulet take its current form and name, given that its own popular 1355 siege-of-Castelnaudary origin story is directly contradicted by the historical record?
Open Cassoulet
Why It Is Open Wikipedia's article on cassoulet reports the popular tradition that cassoulet was invented in 1355 during a siege of Castelnaudary, then states plainly that in historical fact there was no siege and the Black Prince sacked and burned the town instead. The same article dates the term cassoulet itself to no earlier than the 19th century per the Dictionnaire de l'Academie francaise, with only the vague label medieval estouffet for an earlier related dish. No source bridges the medieval estouffet and the 19th-century named cassoulet, so origin-start-year and origin-end-year are left unfilled rather than built on the disproven 1355 legend.
What Would Settle It A documented dating of the transition from the medieval estouffet to the dish and name cassoulet, replacing the disproven 1355 siege legend with real textual evidence.
Expertise Needed food history
Question posed in
Cassoulet (Wikipedia), History section: 1355 siege legend refuted, term dated no earlier than 19th century.
Gallo Pinto
What year, and in which country, did gallo pinto (the Central American rice-and-beans dish) actually originate?
Open Gallo Pinto
Why It Is Open Costa Rica and Nicaragua each claim the dish with contradictory dates: Costa Rican tradition dates it to 1930s San Jose via a specific farmer's-feast origin story; Nicaraguan tradition holds it derives from a dish brought to the country by enslaved Africans considerably earlier. Wikipedia's own account calls the country of origin uncertain and disputed, and notes only general agreement that the dish's roots are Afro-Caribbean.
What Would Settle It A documented pre-1900 written or oral-history source placing a recognizable gallo-pinto-style rice-and-bean preparation in one country specifically, or a scholarly source adjudicating between the competing Costa Rican and Nicaraguan origin narratives.

Buddhist Vegetarianism (Buddhist Dietary Practice)
When did Buddhist monastic vegetarianism become a settled, codified practice, closing the origin period Ashoka's Rock Edict 1 (c. 257 BCE) began?
Open Buddhist Vegetarianism (Buddhist Dietary Practice)
Why It Is Open Ashoka Rock Edict 1 (c. 257 BCE, already recorded as this entity's origin-start-year) shows royal commitment to vegetarianism and a ban on animal sacrifice in the Maurya Empire, but the sources consulted (the Buddhist vegetarianism and Buddhist cuisine Wikipedia articles, and the Emperor Wu of Liang Wikipedia article, checked for a later Chinese Buddhist monastic vegetarianism edict) describe the Theravada/Mahayana divergence on meat-eating as gradual, unfolding over centuries with no single codifying event or year named.
What Would Settle It A dated primary or secondary source naming a specific edict, monastic code revision, or council ruling that formally codified Mahayana monastic vegetarianism, giving a defensible close to the origin period Ashoka's edict began.
Expertise Needed Buddhist religious and food history
Question posed in
Buddhist vegetarianism (Wikipedia), Views of the three Buddhist vehicles section, Theravada view subsection.
Agnolotti
When and where did agnolotti take shape as a distinct stuffed pasta in Piedmont?
Open Agnolotti
Why It Is Open The only origin account Wikipedia gives is a legend that the name comes from a cook called Angiolino, or "Angelot", from Montferrat, said to be the inventor of the recipe; no date or period is attached to this legend and the article gives no other historical dating for when agnolotti took shape.
What Would Settle It A food-history source establishing when stuffed pasta of this square-folded Piedmont form was first made or documented, independent of the undated Angiolino naming legend.
