Annatto Seed, (Bixa Orellana) is the seed from a flowering tree of the Bixaceae family. This tree is also known as a "lipstick tree" because much of the red color found in lipstick is derived from the dye in the pulp that surrounds the Annatto Seeds. As a spice, Annatto is used most often in the Caribbean and Central America. Besides coloring foods, Annatto also imparts a mild flavor. Annatto Seed is an ingredient in achiote paste. Annatto Seeds are small, triangular shaped, about 1/2 cm wide and velvet red with a soft texture.
