Place all ingredients in the blender. Fill the blender half way up with water and emulsify ingredients until smooth.
Make sure that you use the same amount of Parsley and Cilantro. Don’t use the stems only the leaves.
You can always add more Garlic and Pepper to make it spicier. I made the recipe white girl mild.
Make sure only to use fresh garlic.
If the sauce is too thin just add more celery.
You can buy jarred Chili Pequin in Latin Markets. These tiny peppers are insanely spicy so use sparingly.
The Vinegar is important to add because it preserves the sauce so that it will last for one month in the refrigerator.
