Prepare the Chilies: (Any spicy pepper works, Thai bird's eye chilies are the standard)
Wash and deseed the red chili peppers for a milder taste or leave the seeds for an extra kick.
Chop the chilies coarsely.
In a food processor, combine the chopped chilies with peeled garlic cloves.
Pulse until you achieve a coarse texture.
Add salt, sugar, and rice vinegar to the chili-garlic blend.
Adjust salt and sugar to taste.
Blend all ingredients until you achieve a smooth, paste-like consistency.
For a citrusy twist, add a splash of lime juice and stir.
I always add lime juice, not everyone does
