Peel and wash 2 heads of medium large sized whole garlic.
Then, put the peeled and washed garlic into the chopper. Mince the garlic into small pieces, don't need to be fine.
After that, wash and cut 20 medium sized red Fresno chili peppers (around 1 pound) into chunks.
Next, put the cut chili peppers into the chopper and chop until they are smaller pieces. (I separate two times to chop the peppers because my chopper is small. If you have a food processor, you can do it all at once.)
The following step, pour ½ cup of vegetable oil into the pan. Turn on medium small fire and heat up the oil.
When the oil is hot, add the minced garlic slowly into the oil. Level the minced garlic and let it simmer for 1-2 minutes.
After, add chopped red chili peppers into the pan.
Mix the garlic and chili peppers well. Then, simmer for 5-6 minutes. Keep stirring once a while.
Add 1.5 tablespoons of salt, 2 tablespoons of sugar and 1 teaspoon of vinegar. Mix it well.
Lastly, let it simmer for another 5-6 minutes. Also, keep stirring once a while.
