Although this pepper is literally named "yellow chili pepper," its color changes to a bright orange as it matures. The chili pods have a thick skin, are 4 to 5 inches long, and are considered hot (it is 30,000 to 50,000 on the Scoville Heat unit scale). Smelling a bit like a raisin, this chili's taste is somewhat subtle with hints of passion fruit and mango, imparting a unique flavor to any dish. The aji amarillo is a member of capsicum baccatum, one of the five domesticated pepper species, and is grown all over Peru. The aji amarillo—aji means chili pepper and amarillo means yellow in Spanish—is considered part of the Peruvian "holy trinity" when it comes to their cuisine, along with garlic and red onion.
