Tamarind Sauce:


Step 1
Mix soy sauce and flour together in a large bowl until blended. Add chicken and mix until coated.

Step 2
Mix water, fish sauce, brown sugar, and tamarind paste together in a bowl.

Step 3
Heat oil in a wok over medium-high heat. Add garlic, chile pepper, and ginger and fry for 1 to 3 minutes. Remove chicken from the marinade and add to the wok; stir-fry for 1 to 2 minutes. Add 1/2 the tamarind sauce mixture to the wok and continue stir-frying until liquid dries up. Add remaining sauce and cook until chicken is no longer pink inside and sauce is thickened to desired consistency, 10 to 15 minutes more.
