Dinner: Chicken Curry with Cashews

In this recipe adapted from Charmaine Solomon's Complete Asian Cookbook, ground cashews thicken the curry and give it a rich, nutty flavor. Both roasted and raw cashews work well, so use whichever you prefer.

Ingredients

1/2 stick (1/4 cup) unsalted butter
2 medium onions, finely chopped (2 cups)
2 large garlic cloves, finely chopped
1 tablespoon finely chopped peeled fresh ginger
3 tablespoons curry powder
2 teaspoons salt
1 teaspoon ground cumin
1/2 teaspoon cayenne
1 (3 1/2- to 4-pound) chicken, cut into 10 serving pieces
1 (14.5-ounce) can diced tomatoes
1/4 cup chopped fresh cilantro
3/4 cup cashews (1/4 pound)
3/4 cup plain whole-milk yogurt
Accompaniment: cooked basmati or jasmine rice
Garnish: chopped fresh cilantro

Instructions

Heat butter in a 5- to 6-quart wide heavy pot over moderately low heat until foam subsides, then cook onions, garlic, and ginger, stirring, until softened, about 5 minutes. Add curry powder, salt, cumin, and cayenne and cook, stirring, 2 minutes. Add chicken and cook, stirring to coat, 3 minutes. Add tomatoes, including juice, and cilantro and bring to a simmer, then cover and simmer gently, stirring occasionally, until chicken is cooked through, about 40 minutes.
