2 to 3 pound of catfish pieces 1 pound of dried prik ki nu haeng (dried greed birdseye chilis) ½ cup of garlic, chopped (including the skins) ½ cup of shallots, chopped (including the skins) 2 tablespoons of kapi (fermented shrimp paste) ¼ cup of fish sauce 3 tablespoons of sugar (preferably palm sugar).
The shallots and garlic are broiled/grilled until the skins blacken, and then peeled and chopped.
The dried chilis are also broiled until they just begin to blacken. This is very critical overdo it and the vapor given off is highly irritating to the nose and eyes! (If nervous, follow the suggestion above about cooking on a cookie sheet, but do it outdoors.)
Deep fry the fish until crispy, then tease off the flesh, discarding the bones. You need 2 pounds of shredded cooked fish.
Combine all the ingredients in a blender or food processor.
Can be kept in a well stoppered jar, or refrigerated.
