There are several similar Thai recipes that consists of a salty thing added to coconut milk to make a rich salty sauce. The saltiness in this one comes from the yellow beans. Many of these recipes are popular in Thailand, but they don't really translate to the west, I think it's because the taste is nice but the sauce isn't much to look at.
250 ml Coconut Milk
5 Tablespoons Yellow Bean Sauce
100 ml Tamarind Juice
2 Tablespoons Sugar
100 gms Pork Mince
50 gms Shrimp Mince
1 Tablespoon Sliced Red Onion
1 Tablespoon Sliced Chillies
1 Tablespoon Chopped Coriander Leaves
1. If you prefer a smooth sauce, blend the yellow beans to a smooth paste, I prefer to have some texture.
2. Boil the coconut milk over a medium heat, add the yellow bean sauce, add the pork mince and the shrimp mince and lower the heat.
3. Add the tamarind juice (tamarind pulp squeezed into water to make sour water), add the sugar and stir tomix.
4. Take off the heat, chop the chillies, coriander and onion and add to the sauce and serve.
