🧀 Ingredients & Substitutions

Avocado: If you need help picking the best avocado, Avocado's from Mexico has a great guide.

Tomatillos: If you aren't quite sure what a tomatillo is or how to find them ( they are easy to find), I have a whole section below on them.

If you don't want to use tomatillos, you can substitute 2 for juice from 1 lime. The overall flavor won't be as complex, but you will get the acid you need for this sauce.

Green Onion: Just use the light green to the dark green part.

Jalapeno Peppers: Remove the stem and seeds before adding to the blender. One jalapeno with no seeds will give you a very mild sauce.

Garlic Clove: A garlic clove will give you better flavor, but you can use ⅛th of a teaspoon of garlic powder in place of fresh garlic.

Water: Water will help to make the sauce creamy. Start off with 2 tablespoons and add more if you want a thinner sauce.

❓ What are tomatillos, and where to find them?

Tomatillos look like small green tomatoes wrapped in a papery green/ brown husk. Inside the husk, the tomatillo is bright green and a little sticky. They have a sour, citrusy flavor.

When buying tomatillos, look for firm, green fruits with intact husks. Avoid the ones with any signs of decay.

To use them, rip off the husks and rinse the tomatillos to remove any stickiness.
They can be found near peppers, tomatoes, or tropical fruit in the grocery store. Each store is different.

I've always been able to find them, and I live in Upstate New York. I think there is a good chance your store has them. If not, you can substitute 2 tomatillos with the juice from one lime.
