Mamaliga from American maize — How a foreign grain became a national dish
Maize came from America and replaced millet and buckwheat. Pick a year and a crop, watch the fields change, then grind and stir the porridge yourself.

Food: what story does the route to the table tell?
Follow ingredients through fields, markets, kitchens and records. Explore where history, taste, cooking tools and access to food meet.
Choose a documentary thread and see what the sources support, from ingredient to question.
At the table · geometry
A wider pizza can cost less for the same amount.
Compare two diameters and prices. The circles show area at the same scale; the price per square centimetre tells you what you pay for it.
The 40 cm pizza costs 8.6% less for the same area.
Area: 804.25 / 1,256.64 cm². Price per 100 cm²: 4.35 / 3.98 lei.
A disc’s area is π × diameter² / 4. These are example prices you can replace, rather than restaurant offers. Lei is Romania’s currency.

Maize and mămăligă
CONTEXTThe Americas · maize’s origin
→EVIDENCE IN THE SOURCECrops and change over time
→WHAT YOU CAN EXPLORERomania · mămăligă
Maize is native to the Americas. Its source project follows changing crops in Romania and how maize became an ingredient in a dish now known as mămăligă. The sources do not reduce this change to one date.
A documentary thread, not a map of one journey or a story of an unchanging recipe.

The bread is Latin, the plow is Slavic
Romanian's basic food words trace to Latin. The heavy medieval wheeled plow's parts are mostly Slavic or Hungarian. An interactive diagram shows where the farming vocabulary splits.

It took corn puffs 27 years to become “traditional”
In 1971, Romanian corn puffs were launched as a new item with pecorino cheese. By 1998, the press called them traditional. A history of factories, patents and the Baia Mare production cluster, reconstructed from the archive.
Ingredients travel; habits change
American maize, potatoes and wheat have different agricultural and food histories. Their source projects keep the records and evidence for each change instead of describing an unchanging Romanian cuisine.

The Potato Used to Be a Truffle: from Italy to Germany and Romania
Cartof comes from German Kartoffel, and Kartoffel from Italian tartufolo: truffle. Seven Romanian dictionaries give the first link, Scriban alone the second. With the 1818 Iași brochure, four cousins around the world and a match-the-names game, in Romanian and English.

When Romania Fed England: the Wheat of Brăila, 1843–1852
Ten harvests, two free ports and the 9-foot Sulina bar: how Brăila and Galați came to send hundreds of thousands of quarters of wheat to 1840s London.
Markets can show abundance or scarcity
Wheat exports, market stalls and a bread ration card do not measure the same thing. Compare figures only after checking period, units and who was included.

London’s pubs, counted: what they are called, how near they are, how many are left
London’s commonest pub name is The Crown, ahead of the Prince of Wales and the Red Lion: 31 of the 3,155 pubs mapped by OpenStreetMap’s volunteers. Half of the city’s postcodes have a mapped pub within 286 m in a straight line, and the official count of pubs and bars fell from 4,835 in 2001 to 3,525 in 2024, with Hackney the only borough that rose. A map of London drawn only from its pubs, with a result and a picture for each of 217 postcode districts.

About the collection
The collection covers crops, trade, ingredients, drinks, words, taste, kitchen tools and access to food. It also includes a few projects about bodily sensations where food is central. Water entries describe taste, composition or footprints; they are not potability recommendations. Current rules and medical sources stay with their own projects.
