Aji amarillo is one of the most important ingredients in Peruvian cooking. With a raisin-like scent, this chili's taste is somewhat subtle with hints of passion fruit and mango, imparting a unique flavor to any dish. Aji amarillo adds spice, interesting flavor, and a beautiful golden color to a dish. Make a simple ají amarillo sauce (crema de ají) to serve with roasted chicken, vegetables, and even French fries.
