How to Keep Mussels Alive
Here's the mussel tip nobody tells you when you buy them for the first time.
Do NOT put them in the fridge. I know that feels wrong... fresh seafood, cold storage, right? Actually no. In the fridge, mussels suffocate from lack of oxygen and die on you overnight. You'll open the bag to sad, dead mussels and a smell you don't want in your kitchen.
What works instead: sea water. Fill a bowl with cold water and add a big handful of sea salt (not mined kosher, not table salt). The minerals in real sea salt actually matter here. Taste it. It should taste briney like the ocean.
Toss the mussels in, add a bunch of ice cubes to keep it cold, cover with a damp towel, and set it in the coolest spot in your kitchen. They'll happily stay alive overnight this way.
I still recommend buying mussels the same day you plan to cook them for the best experience. But when life shifts and dinner moves to tomorrow, this is the trick that saves the meal.

Do you cook mussels are home or only eat them at restaurants?
