Because we live in Peru, friends back home often ask us how to make Peruvian ají (chili) sauce. Spicy, addictive and a striking shade of green, this unique sauce or salsa is quick and easy to prepare. Traditionally served with rotisserie chicken and French fries, it is also delicious spooned over potatoes, fish or beef. Or serve this sauce as a dip with bread cubes, fresh veggies or potato chips.

Recipes for the sauce vary from region to region, and depending on the hot peppers you choose, it may also be yellow or orange in color. Two main ingredients in ají sauce are cilantro and hot chiles. In the United States, jalapeno peppers are easy to find and make a tasty sauce. In Peru, two common ingredients are the herb huacatay and the hot pepper ají amarillo (ají marisol). Authentic Peruvian ají sauce won't contain mayonnaise or lettuce.

Tips for Making Peruvian Ají Sauce

  • If serving the sauce over potatoes, you may want to thin it with a little milk, cream or vegetable oil. To thicken a sauce, Peruvian cooks add one or two saltine crackers or a piece of dry bread before blending.
  • You can substitute 1/3 cup drained cottage cheese for the feta cheese or queso fresco.
  • Increase salt if using cottage cheese or queso fresco.
  • Peruvian ají sauce can vary from mild to spicy depending on the peppers you choose. If you'd like more heat, don't remove the veins or seeds from the peppers.
  • Any hot pepper can be used in place of jalapenos. Feel free to experiment with hot peppers from your garden and tell us about it in the comments section.
  • The optional peanut butter adds depth without overpowering the sauce and is a typical ingredient in some regions of Peru. Try ají sauce first without peanut butter and then with it. We like it best with the peanut butter.
  • Serve with a tall glass of cool Peruvian Chicha Morada for an authentic experience.

Questions & Answers

Question: Can Peruvian Aji sauces be frozen?

Answer: I have never frozen the sauces. It’s possible they could separate when frozen. In Peruvian homes, sauces are eaten fresh. If you try it, please let me know how it turns out.

Question: Can Peruvian aji sauces be made with mayo?

Answer: I have seen recipes that add mayonnaise to Peruvian aji sauces. I have tasted them and although they are delicious, it is not authentic. In Peru, mayonnaise is never added to aji sauce.
