One of my favorite meals is a big pot of fresh, flavorful steamed mussels. Steamed clams are also high up there, especially in the summertime. If you're not familiar with cooking these bivalves at home, know this - they're easy to make with just a few basic ingredients and they're really affordable.
Mussels and clams do require a bit of cleaning, but it's a trade-off I'm happy to take. When I was in culinary school, I learned a simple but extremely useful tip for cleaning and making extra-plump mussels and clams every time. It involves just water, salt, and a bit of flour.
