In a small saucepan, bring the shallots, pepper, clove of garlic, trassi, galengal, tamarind, palm sugar, key lime leaves and salt to the boil with about a cup and a half of water.
Stir in the peanut butter.
Let it come to a boil again, add the creamed coconut and stir until dissolved.
Finish with the ketjap manis to give the sauce a slight gloss.
When the sauce has cooled completely,either mix it into the cabbage, carrot and spring onion to make a coleslaw for Indonesian chicken and waffles or add a nice big dollop of it to a pretty plate of mixed veggies, tofu puffs, new potatoes and boiled eggs.
