Start by peeling the garlic cloves and washing the chili peppers.

Remove the stems from the peppers and chop them roughly.

In a medium saucepan, combine the chopped peppers, garlic, vinegar, salt, and sugar.

Bring the mixture to a boil, then reduce to a simmer for 15 minutes.

Once everything is softened, carefully transfer the mixture to a blender.

Blend until smooth.

If the sauce is too thick, add a little water or extra vinegar to desired consistency.

Taste and adjust the salt or sugar as needed.

Let the sauce cool down before transferring it to a glass jar or bottle.

Seal the container and store it in the refrigerator.
