About Recidemia

What is Recidemia?

Recidemia is an open encyclopedia of world recipes, organized using the Recidemia Culinary Index (RCI) — a hierarchical numbering system inspired by the Aarne-Thompson-Uther (ATU) index used in folklore studies. Every recipe type receives a unique, structured identifier that encodes its place in a four-level taxonomy: Domain, Family, Type, and Variant.

The goal is to create a comprehensive, scholarly reference for the world’s recipes, making them searchable, citable, and interconnected across culinary traditions.
