The aji amarillo chili pepper is a spicy South American pepper with vibrant orange-yellow skin and fruity flavor. “Amarillo” means "yellow" in Spanish, and “Aji” means "chili" in South America, this pepper is also appropriately known as the “yellow chili.” The Ají Amarillo is grown in all areas of Peru. Used by the Incas, it is still the most common and popular chili pepper in that country.
It may be said that is it possibly the most important ingredient in Peruvian cuisine, as it is incorporated in a number of national dishes, from main courses to side dishes and more. You'll find them at Peruvian markets in many forms, including fresh and dried, canned or chili paste.
Aji Amarillo paste is very common and used in many spicy recipes as well, including the famous and wonderful Aji Amarillo sauce, which is a national favorite.
What Does the Aji Amarillo Look Like?
The Aji Amarillo pepper grows to about 4-5 inches in length, and despite its name, it actually matures to a deep orange. The skins are vibrant and smooth, though slightly rippled. The color can vary from pod to pod as they mature, from a bright orange to deep, deep orange.
What Does the Aji Amarillo Taste Like?
Like other peppers from this area, the Aji Amarillo has a fruity, berry-like flavor. It is medium in heat level, but it does not leave your mouth burning. It is also great as a condiment.
I find the flavor of fresh aji amarillo peppers to be quite vibrant, which makes them great for making sauces, salsas, or drying and grinding into powders.
It's definitely a must for Peruvian food, prized for their unique flavor.
How Hot is the Aji Amarillo?
It is often asked, are aji amarillo peppers hot? On the Scoville Scale, the Aji Amarillo ranges from 30,000 - 50,000 Scoville Heat Units (SHU), which is about as hot as a serrano pepper.
Compare this to a typical jalapeno pepper, it can be up to 10 times hotter.
What Can I Substitute for Aji Amarillo?
If you're unable to find these peppers or cannot grow them, you can usually substitute them for the more commonly found habanero pepper or Scotch Bonnet pepper.
Beware, however, as both of those peppers are quite a bit hotter than the aji. They're similar in flavor profile, though, and have a nice fruitiness.
If you'd like to tame the heat of those substitutes, core them out to remove the innards, which is where most of the heat resides. Or, you can use milder sweet bell peppers, either yellow, orange, or red, for similar flavor with no heat.
Where Can I Buy Aji Amarillo Peppers?
The Ají Amarillo may be sold in Latin food stores and on the internet in its dried or paste form.

Can you eat this pepper green? Before it is ripe?
A storm blew over our plants and we have probably 20 peppers that were knocked off the plants. Good size, too! Don't want to waste them....
Michael Hultquist - Chili Pepper Madness says
You sure can, Gay. They will taste more "green", or under ripe, but definitely still edible. You can also try to ripen them up a bit on the sunny windowsill.

A pepper sauce of this went into Poke. A great taste of fruitiness! I chewed on the seeds for a little more burst of heat. An excellent complement to Poke or Ceviche! In my opinion, it is more 'fruity' compared to Habanero, Serrano, or Jalapeno peppers.
I want to try and add to home made coleslaw (not mayo-soaks store type) and put on fish tacos.
Michael Hultquist - Chili Pepper Madness says
Such a wonderful pepper, isn't it? Love it.
