annatto seeds

Herbs & SpicesYear-round; annatto seeds are dried and shelf-stable, though fresh pods are harvested in late summer and early fall in tropical regions.

Annatto seeds are low in calories and primarily valued as a colorant rather than a nutritional source, though they contain small amounts of minerals including iron and contain the carotenoid compound bixin with potential antioxidant properties.

About

Annatto seeds are the small, hard seeds of the achiote tree (Bixa orellana), a tropical shrub native to Central and South America and the Caribbean. These rust-colored seeds are enclosed in a distinctive spiky, reddish-brown pod and have a thin, waxy outer layer that contains the pigment bixin, responsible for their vibrant orange-red color. The seeds possess a subtle, earthy flavor with faint peppery and slightly nutty notes. Annatto is widely used as a natural colorant in both traditional and commercial food production, valued for its ability to impart a golden-orange hue without significantly altering taste.

Annatto seeds can be used whole or processed into powder or paste. The coloring compound is fat-soluble, making annatto seeds traditionally infused in oils or lard before being added to dishes. Regional variations exist across Latin America, the Caribbean, and parts of Asia, where it has become established in Southeast Asian cuisine.

Culinary Uses

Annatto seeds are used primarily as a natural food colorant and seasoning agent across Latin American, Caribbean, and Philippine cuisines. In Mexico and Central America, achiote paste is rubbed onto meats for cochinita pibil and other regional specialties; in the Caribbean, the seeds are infused into oils and fats to color rice, stews, and seafood dishes. The seeds are also ground into a powder used in spice blends and marinades, and they traditionally color cheese, butter, and other dairy products. Preparation typically involves steeping whole seeds in hot oil or lard to extract color and flavor, or grinding them into a paste with other spices and acidic ingredients.
