Aji Amarillo peppers are a type of chili pepper that is common in Peruvian cuisine, known for their unique, fruity flavor and cayenne-like medium heat level. The name “Aji Amarillo” translates to “yellow chili” in Spanish, but these peppers, when fully mature, actually turn a bright orange color. They measure between 30,000 to 50,000 on the Scoville scale.
Aji Amarillo peppers are incredibly versatile and are used in a variety of dishes, including sauces, stews, and ceviche. They are often used fresh or in paste form to add depth and complexity to dishes. The peppers have a unique flavor profile that is slightly fruity with a hint of passion fruit and raisin, which sets them apart from other chili peppers. Despite their heat, Aji Amarillo peppers are celebrated for their flavor as much as their spiciness.

How hot is the aji amarillo?
At 30,000 to 50,000 Scoville heat units (SHU), the aji amarillo matches the spiciness of cayenne peppers and tabasco chilies. It sits right in the middle of the medium heat range of the Scoville scale. Comparing it to our jalapeño reference point, the aji amarillo is four to twenty times hotter than a jalapeño pepper. It’s noticeably spicy, but cayenne sits on many spice racks, so this is a heat more than a few can enjoy.
Let’s also compare it to some other popular Peruvian chili peppers. The aji panca is a mere blip on the scale, running a mild 1,000 to 1,500 SHU. The lemon drop pepper (also known as aji limon) is slightly milder (15,000 to 30,000 SHU.) And the Peruvian white habanero is much spicier, running the typical 100,000 to 350,000 SHU of common habaneros.

What does it look like and taste like?
The name “yellow chili” speaks to the look, of course. But as the aji amarillo ages, it turns from yellow to a sun-like bright orange. They grow to four or five inches long, with a slim chili body and thick juicy walls.
In terms of the flavor, this is one of the best tasting chilies out there. The aji amarillo has a clean, sunny taste; hints of tropical fruit; and a slightly raisiny finish. Some compare the fruity flavor to a scotch bonnet pepper (but much milder), and that’s about right. Though we find the scotch bonnet to be slightly fruitier and the aji amarillo to be more bright in taste. Its flavor profile, broader shape, and lesser heat than the scotch bonnet make it more usable across a variety of recipes and cooking methods.
Dried aji amarillos lose some of the sweetness and take on a lightly smoky, sunburnt taste. The raisiny finish is more pronounced. Think of it somewhat like the difference between a fresh tomato and a sundried tomato.
Cooking with aji amarillo
In Peru, this chili is gully engrained in their cuisine. Any authentic Peruvian cookbook will be chock-full of recipes calling for the aji amarillo. Peruvian ceviche is a popular authentic use, as is papa a la huancaina (boiled potatoes topped with a fiery cheese sauce.)
But really, the versatility of this chili is a big part of what makes it special. Its fruitiness makes it terrific in hot sauces and salsas, and it tastes quite good fried with a little olive oil and sea salt as a side dish. Try them raw, too, mixed into a refreshing summer salad. The pairing of goat cheese and aji amarillo over greens is a simple, yet special treat.

- Learn how to combat chili burn. That’s the downside of cooking with any chilies. It’s very easy to get the uncomfortable burn from handling them, particularly when cut open. Read our post on how to remedy that burning sensation. Milk is your best option, but there are many more.

I am going to make a Peruvian salad for a Spanish-language class presentation and the recipe calls for fresh aji amarillos. As I can’t find any fresh ones here in southern Oregon, I ordered some paste from Amazon so I can at least approximate the taste — if not the appearance or texture — in the recipe. Do you have a good substitution ratio to use? I would be mixing the paste into a marinade of oil, vinegar, and lime juice. The recipe call for ONE fresh chili. Thanks for any suggestions!
