Aji Amarillo, the yellow-orange chile, also known as Aji Escabeche, is one of the more common Peruvian chiles and ranges between 2,500 to 10,000 on the Scoville heat unit scale. Fresh tropical fruit and berry aroma make this chile at home in BBQ sauces, hot sauces, chili, stews, and tomato-based soups.
