Ingredients

• 8 cups water
• 1 cup wild rice
• 1 3/4 teaspoons salt
• 1 cup hard wheat berries*
• 2 ounces dried porcini* (2 cups)
• 2 pounds skinless boneless chicken breast halves (6 small or 4 large)
• 1/4 teaspoon black pepper
• 1 tablespoon vegetable oil
• 1 tablespoon unsalted butter
• 3 large garlic cloves, minced
• 1/2 cup dry white wine
• 1 (14- to 16-ounces) can diced tomatoes, drained
• 1/3 cup chopped fresh dill
• Special equipment: an electric coffee/spice grinder
• Garnish: chopped fresh dill

Instructions

1. Bring 4 cups water to a boil in a 2-quart heavy saucepan, then add rice and 1/2 teaspoon salt. Reduce heat to low and simmer, covered, until rice is tender and grains are split open, 1 to 1 1/4 hours (not all liquid will be absorbed). Drain in a colander.
2. Cook wheat berries while rice simmers: Bring remaining 4 cups water to a boil in a 3-quart heavy saucepan, then stir in wheat berries and 1 1/4 cups porcini. Reduce heat and simmer, partially covered, over low heat until wheat berries are tender, 1 to 1 1/4 hours. Stir in 1/2 teaspoon salt and pour wheat berry mixture into a large sieve set over another saucepan or a skillet. Reserve wheat berries and porcini in a bowl and boil cooking liquid until reduced to about 1 cup, then add to wheat berry mixture. (Cut up any porcini that are large.)

Reduce heat and simmer, partially covered, over low heat until wheat berries are tender, 1 to 1 1/4 hours. Stir in 1/2 teaspoon salt and pour wheat berry mixture into a large sieve set over another saucepan or a skillet. Reserve wheat berries and porcini in a bowl and boil cooking liquid until reduced to about 1 cup, then add to wheat berry mixture. (Cut up any porcini that are large.)
4. Cook chicken: Put oven rack in middle position and preheat oven to 450°F. Grind remaining 3/4 cup porcini to a powder in coffee/spice grinder. (If porcini are too moist to grind, dry completely on a baking sheet in oven 3 to 5 minutes, then cool before grinding.) Pat chicken dry, then arrange in 1 layer on a sheet of wax paper. Sprinkle both sides of chicken with remaining 3/4 teaspoon salt and season with pepper. Put porcini powder in a fine mesh sieve and dust both sides of chicken generously, shaking off excess. Heat oil and 1/2 tablespoon butter in a 12-inch heavy skillet over moderately high heat until foam subsides, then brown chicken in 2 batches, without crowding, turning over once, about 4 minutes per batch. Transfer chicken to a shallow baking dish as browned (reserve fat in skillet). Bake browned chicken until just cooked through, 3 to 5 minutes, then let stand 5 minutes before slicing.

9. While chicken bakes and stands, add remaining 1/2 tablespoon butter to fat in skillet and cook garlic over moderately low heat, stirring, 1 minute. Add wine and boil over high heat, stirring and scraping up brown bits, until reduced by half, about 3 minutes. Add wild rice, tomatoes, and wheat berry mixture (including reduced cooking liquid) and bring to a boil, stirring occasionally. Stir in dill and season with salt and pepper. Slice chicken and serve with rice mixture.
