Mussels are relatively inexpensive, and they’re also environmentally friendly. Because farmed mussels are grown suspended in water, there is no dredging the ocean ﬂoor to harvest them. To make sure mussels are alive, tap them to see if their shells close. Toss any mussels that do not close. Mussels cook quickly and can be steamed, smoked, grilled, and baked. Steamed mussels are easy and it's fun to experiment with the broth. Combining coconut and basil is delicious, like in this recipe.
