Annatto is an orange-red Latin, Filipino and Caribbean condiment and food coloring derived from the seeds of the achiote tree.It is often used to impart a yellow or orange color to foods, but sometimes also for its flavor and aroma.
Also known as achiote, they are used to impart a bright golden color to oils, rice dishes and meats. They lend a tangy, slightly bitter, earthy flavour as well. It is also used to flavour and colour butter, smoked fish and homemade cheese.
Annatto seeds are sold in 1/2 cup measurements in a resealable, air tight bag.
