I once burned 200 mussels in a row before I figured it out. Okay, that’s an exaggeration—I only burned 199. The point is: you’ll learn by failing. Start with a cheap bag from the grocery store, not a fancy French bistro batch. And remember: when in doubt, undercook by a minute. You can always steam them again, but you can’t un-rubber a mussel.
So next time you face a pot of these black-shelled goblins, stay calm. Watch for the open, poke for the spring, and sniff for the ocean. Cooking mussels is 80% science, 10% luck, and 10% pretending you know what you’re doing. Now go forth and steam like nobody’s watching—but maybe keep the wine glass full. Cheers.
