What is Aji Amarillo?

Aji amarillo is a vibrant yellow-orange chili pepper native to Peru, considered the cornerstone of Peruvian cuisine. With a medium heat level and distinctive fruity flavor profile that hints at mango and sunshine, it delivers warmth without overwhelming spiciness. Home cooks can find aji amarillo as fresh peppers, frozen, dried, or in convenient paste form, which is most commonly available in international markets. This versatile pepper brings both color and depth to classic dishes like papa a la huancaína (potato with cheese sauce), ceviche, and aji de gallina (creamy chicken stew). Its unique taste can transform ordinary sauces, marinades, and dips into something memorably flavorful.
