Annatto is called the lipstick tree because its red seeds impart a deep rich color, whether used for makeup, dying cloth, or cooking food. It is used in Caribbean and American cuisines to provide a bright red or yellow color to sauces, roasted meats and poultry (similar to how turmeric is used in Asian cuisine). Its dry earthy flavor and bright color provide the backbone for many colorful and flavorful dishes, such as mole.
Protip: heat ½ tbsp of annatto in 1 cup of oil or water, then strain, for a bright golden infusion you can add into cooking grains, vegetables, or meat.
