4 tablespoon oil
         3 tablespoon chopped garlic
         3 tablespoon chopped shallots
         3 tablespoon coarsely chopped dried red chiles
         1 tablespoon fermented shrimp paste
         1 tablespoon fish sauce
         2 teaspoons of sugar
 heat the oil: add the garlic and shallots and fry briefly, remove from
 the oil and set aside. Add the chilies and fry until they start to

 and shallots, blending each in before adding the next. Then over low
 heat return all the ingredients to the oil, and fold into a uniform
 The resulting thick, slightly oily red/black sauce will keep almost

 get the flavour you want.
