The fish guy at the supermarket had arctic char (one of our very favorite fishes) a couple of weeks ago, but we had other plans for dinner that night. I asked him if he thought it would keep until Friday if I bought some that day, and he gave me a firm “nope.” Sigh.
But char doesn’t come around every day. Feeling uncharacteristically optimistic, I bought a filet anyway and stuck it directly into the freezer when I got home. The following week, I thawed it out and improvised a meal to go with it. And it worked, hurrah!
