Huacatay (Tagetes minuta), also known as Peruvian Black Mint or Wild Marigold, is a tall, aromatic annual herb in the Asteraceae serving as the signature flavoring herb of Peruvian and Andean cuisine. Its complex flavor — combining mint, basil, tarragon, and citrus with a distinctive, almost medicinal undertone — is irreplaceable in traditional Peruvian dishes and impossible to substitute with any other single herb.
• The signature herb of Peruvian cooking — used in the same way basil defines Italian cuisine
• The flavor is completely unique — described as mint meets basil meets tarragon meets citrus, with a hint of anise
• Also called "black mint" due to the dark color of the dried herb
• A member of the marigold family (Tagetes) — related to ornamental marigolds
• Grows as a tall, vigorous weed in many tropical regions but is treasured in Peru
• The essential oil is used in perfumery and as an insect repellent

Dato curioso
Huacatay is considered the "secret ingredient" of Peruvian cuisine — without it, authentic aji de gallina, ocopa, and many other iconic Peruvian dishes are simply impossible to make correctly. Peruvian chefs consider it as essential as salt, yet the herb is virtually unknown outside of South America.
