I was in Vietnam last week, and had several wonderful meals at Quan An Ngon, in Saigon (HCMC). One dish in particular I would like to try to make at home was a Crab cooked (stir fried I think) in a Tamarind sauce. The sauce contained Tamarind, sugar, onions, garlic and chile peppers. It was that perfect mix of tart-sweet-hot. The sauce stuck to the crab and was an absolute gooey mess to eat, but was wonderful.
I have not been able to find a recipe for it, or think of how I could recreate it at home. Any suggestions of where I could find it, or does someone have an idea of how to make the sauce?
Any thoughts are appreciated.
