Paired with some crusty bread and a simple salad, mussels make a lovely light meal. But getting them perfectly cooked can be tricky, with most stovetop recipes inevitably turning out some overcooked and some undercooked mussels. We made cooking mussels absolutely foolproof by using our multicooker, which evenly surrounded the mussels with steam and resulted in a pot full of tender, plump mussels every time. On the pressure setting, we needed to cook the mussels for just 1 minute; on the slow cook setting (which heats up much faster than a traditional slow cooker) the mussels were cooked perfectly within half an hour. To infuse the mussels with lots of flavor, we sautéed garlic, thyme, and red pepper flakes in butter, and used wine as the cooking liquid. We finished the mussels with a sprinkle of fresh parsley. You can substitute 3 pounds of littleneck clams for the mussels; increase the pressure cooking time to 2 minutes. Discard any raw mussels with an unpleasant odor or with a cracked or broken shell or a shell that won’t close. Serve with crusty bread.
