The Food Lab: Better Home Cooking Through Science

Storing

As with asparagus or corn, the best way to store fish
is not to. You should plan on buying it just before
you’re going to take it home, put it in the fridge as
soon as you get there, and cook it within a few
hours.
If you must buy your fish the day before or even 2
days before, keep it as cold as possible. With very
clean hands, rinse the fish thoroughly under cold
running water to wash away any surface bacteria,
then carefully pat it dry with paper towels. Transfer
