Chicken Curry With Cashews Recipe

Directions:

1. 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.
2. Add curry powder, salt, cumin, and cayenne and cook, stirring, 2 minutes.
3. Add chicken and cook, stirring to coat, 3 minutes.
4. 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. (If making ahead, see cooks' note, below.)
5. Just before serving pulse cashews in a food processor or electric coffee/spice grinder until very finely ground, then add to curry along with yogurt and simmer gently, uncovered, stirring, until sauce is thickened, about 5 minutes.
