Peel garlic and cut the stem off from pepper. Add garlic, peppers and salt into food processor. Chop the peppers until they are roughly ground.
Cooking
Scoop out the mixture into a jar. Pour the vinegar in. The vinegar should cover the pepper mixture. The chili garlic sauce will thicken over time. You may need to add more vinegar to keep the mixture submerged.
