In Thailand, it is used as a flavor enhancer to salt dishes, thicken sauces, and increase the intensity of spices. In curries, in particular, it is the shrimp paste that provides that sweet and salty side that makes all the difference between a good curry and a basic curry.
When used in the right proportions, shrimp paste can balance the flavors of a dish. Simply add a teaspoon to your curries or rice dishes.
