Aji Amarillo Puree

Taste of peru

Scoville heat units (SHU): 30,000 - 50,000

Jalapeño reference point: 4 - 20 times hotter

There are so many flavours that converge in the aji amarillo pepper – a sun-drenched crispness, a fruity turn from the tropics, and even a hint of raisin.  Between the flavours, the yellow-golden hue, and a sultry medium-heat, it’s like summer kissed these chillies. Aji amarillo is so delicious that it’s truly the chilli of a nation. For Peru, it’s one of the pivotal ingredients used in their regional recipes – from hot sauces to salad toppings, it’s a staple of their cuisine. Outside of Peru, they are much tougher to find, but, obviously, well worth the hunt.

What does aji amarillo mean? What’s the history if this chili?

In Spanish, aji means “chilli” and amarillo means “yellow”, so simply aji amarillo is a “yellow chilli”. Logical, yes, and it belies the generations this chilli has impacted. Aji amarillo has been a staple of Peruvian cuisine for hundreds of years. In fact, the Incas used this chilli which speaks to its long heritage. It’s other name – Peruvian pepper – is truly more to the point. This is a chilli that heats the blood of a nation and has done so for years.

How hot is the aji amarillo?

At 30,000 to 50,00 Scoville heat units, the aji amarillo matches up with cayenne pepper and tabasco chillies. It sits right in the middle of the medium heat section of the Scoville scale. Comparing it to our jalapeno reference point, the aji amarillo is four to twenty times hotter. It’s not so mild as to merely be a simmer and not so hot as to turn off all but the serious spicy food fans. It’s a heat that pushes the envelope, but doesn’t burn it up.

What do aji amarillo taste like and look like?

The name “yellow chilli” speaks to the look, of course. But as the aji amarillo ages, it turns from yellow to a fiery orange, sort of like the sun itself. They grow to four or five inches in length, with a slim chilli body and thick juicy walls.

There are so many flavours meshing together in the aji amarillo – a clean sunny taste, hints of tropical fruit, and a slightly raisiny finish (that’s highlighted when this chilli is dried). Some compare it to a Scotch bonnet pepper in flavour (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. The aji amarillo’s flavour profile and broader shape just makes it a little more usable across a variety of recipes and cooking methods.

How are aji amarillo peppers typically used?

In Peru, this chilli has permeated their cuisine. Any authentic Peruvian cookbook will be chock-full of recipes calling for the aji amarillo. Really, the versatility of this chilli 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 no doubt a simple, yet special treat.

There really is so much to love about this chilli pepper. It has a unique flavour, a rich history, and a very eatable heat. Introducing the aji amarillo to your kitchen – especially in its native Peruvian cuisine – can open your eyes to whole new worlds of taste.
