2 ¼ pounds skinless, boneless chicken thighs, cut into chunks
2 teaspoons curry powder
1 teaspoon salt
½ teaspoon garam masala
2 onions, chopped
2 tablespoons water
1 tablespoon minced garlic
2 teaspoons paprika
1 teaspoon minced fresh ginger
½ teaspoon cayenne pepper
5 teaspoons corn oil
2 tomatoes, chopped
1 tablespoon fish sauce
1 teaspoon minced lemongrass
1 cup water
Rub chicken thighs with curry powder, salt, and garam masala; cover and set aside. Combine onions, 2 tablespoons water, garlic, paprika, ginger, and cayenne pepper in a blender; blend into a smooth paste.
Heat oil in a large, lidded skillet over medium heat. Add onion-spice paste; cook and stir until darkened, about 7 minutes. Stir in chicken thighs; cook 3 to 4 minutes. Add tomatoes, fish sauce, and lemongrass; cook 2 minutes. Stir in 1 cup water; bring to a boil. Cover skillet and reduce heat to low; cook until chicken begins to fall apart, stirring occasionally, 25 to 35 minutes. Uncover skillet; increase heat and cook until sauce is reduced, about 5 minutes. Skim and discard excess oil from top.
