Arroz AmarilloAchiote (annatto) seeds' color infuse into the cooking oil to give this Mexican rice its typical yellow hue, elusive aroma, and subtle flavor that's typical in Yucatán and along the Gulf coast of Mexico. The red-orange seeds can be found in Latin-American food stores, or in the Mexican section of most supermarkets. Achiote is used all over Mexico for this popular variation on rice, and it often contains fresh mint (but omit it if you like).
