The tomatillo is a tart, green-fleshed fruit of the nightshade family, encased in a papery husk and used as a vegetable in Mexican cuisine. It is the foundational ingredient of salsa verde and a staple of Mesoamerican cooking.
History & Origins
The tomatillo was domesticated in pre-Columbian Mexico, where Aztec and Maya cultures cultivated it long before Spanish contact; Bernardino de Sahagún's 16th-century Florentine Codex describes its use in sauces alongside chili peppers. It was carried back to Europe after the conquest but never gained the prominence of the tomato, remaining closely associated with Mexican and Central American cookery. Today it remains a cornerstone of traditional Mexican foodways and has spread internationally through the popularity of salsa verde.
