Step 1

Wash the chilies then remove the stalks.

Step 2

Put the chilies in a blender. Add the garlic and cooking oil. Blend for a few seconds until it becomes tiny bits. Do not over-blend.

Step 3

After blending, pour in a large pan. Cook in low medium heat while stirring continuously. Cook for around 20 to 25 minutes until the chili changes color.

Step 4

Then, add the other ingredients. Add the sugar, salt, black pepper and oyster sauce. Stir until well blended.

Step 5

Add vinegar. After adding vinegar, do not stir for 3 minutes. Just let it boil. This is to avoid “raw taste” of the vinegar. After 3 minutes, stir and cook for another 20 minutes.

Step 6

Once the chili and garlic is cooked, remove from heat and let it cool completely.

Step 7

Put in a clean dry jar with lid.
