Achiote, also known as annatto, is a spice derived from the seeds of the achiote tree. It is commonly used in Mexican, Caribbean, and Latin American cuisine to add a vibrant orange-yellow color and a slightly nutty, peppery flavor to dishes. However, if you are unable to find achiote, there are several substitutes you can use to achieve a similar taste and color. Turmeric, paprika, saffron, and cumin are popular alternatives that can be used in place of achiote in recipes. Additionally, if you have access to annatto powder, this can be used interchangeably with achiote in many recipes.
