Soaking chicken in salt water gives you a juicier bird. This is why kosher chickens, which are brined before you buy them, often taste better than other chickens. Dissolve 1/4 cup of kosher salt in 1 quart of water and brine your chicken in the refrigerator for at least 6 hours or up to a day before cooking.
A heavy, tightly lidded casserole traps moisture that’s released from the roasting bird, so the juices baste the bird while it cooks. And the moist heat inside the casserole cooks the chicken without drying it out the way a hot oven does.
Chicken pieces cooked without crowding in a skillet will render their own fat, forming a crusty surface that traps the juices inside.
