“Aji” is actually what most South Americans call chiles, and in Peru, the most popular and important ingredient in regional dishes happens to be Aji Amarillo. These spicy chiles mature from green into a deep orange when ripe. An average sized yellow chile is around 12.7 cm in length, but it can get between 15 and 18 cm long. Aji Amarillo has a unique fruity flavor and a subtle spice that is less harsh and more full-bodied. Besides, it ranks between 30,000 and 50,000 on the Scoville scale, and is most often used in recipes as a paste. The chiles are also typically dried and used as a ground spice in a variety of dishes. Capsaicin in chile peppers acts as an anti-inflammatory, which makes it great for reducing swelling and pain in those who suffer from arthritis. Besides, it kills bad bacteria in the stomach and intestines, and often this bacteria is what leads to stomach ulcers.
