The idea of putting supper in one pot, setting it in the oven, and walking away until the timer goes off isn't a novel one. But it's a pretty terrific system. We haven't had much luck getting a slow cooker to give us food with any flavor, but now that we both own handsome Le Creuset enameled cast-iron casseroles - Sheryl found them at T.J. Maxx for a bargain price - we've been cooking in them every night. Of course, any heavy-based pot with a tight-fitting lid will do. The juices are locked in, and the food is loaded with flavor. We make a vegetarian dish with whatever market produce looks good that day. Beef stew begins with a chuck roast that cooks to melting tenderness with Dijon mustard and tomatoes. Stewed chicken thighs make a simple dish that relies entirely on the poultry for flavor. Most nights, the pot goes directly to the table. Family members help themselves, and the cleanup crew has it easy.
