   8      tablespoons   crunchy peanut butter
   1      medium        onion -- finely chopped
   1      cup           thick coconut milk -- (not sweetened )
   1      tablespoon    brown sugar -- or palm sugar
   1      teaspoon      cayenne*
   1      stalk         lemon grass -- finely chopped
   1      tablespoon    fish sauce -- nam pla
   1      tablespoon    dark sweet soy sauce

Preparation:

In a sauce pan combine all the sauce ingredients and bring to a simmer, stirring, until you reach the desired consistency. (5 to 10 minutes) Remove from the heat and serve in small bowls as an accompaniment. * I use two to three teaspoons of freshly ground cayenne. This can be made by grinding crushed red or whole dried red peppers in a coffee grinder, there is a significant difference in taste and heat.
