I noticed that H2O Life is selling individually quick-frozen "silversides." While that is WAY more convenient than the block-frozen ones from SF Bay, the fact that H2O Life uses blue anchovies (which are very likely to contain thiaminase, as two other species of anchovies are on "The List") put me off. So I took matters into my own hands...

First I let the SF Bay flat thaw just a little, so I could start breaking off chunks of it. Then I let each chunk thaw until I could just separate all the fish. Then I sorted the fish by size (ones my boys can swallow now, ones they're not going to be able to swallow for a good long while...) and laid them out individually to re-freeze:


After re-freezing I vacuum sealed the sorted fish for storage:


I figured the fact that the fish all got mostly thawed once and then re-frozen is still better than having to thaw the whole flat a little bit each time I wanted to break off some of the fish. And the size sorting means I now don't have to decide what to do with the occasional mondo fish that's way too big for my boys, even cut lengthwise.

Tangent: I found this little "exchange student" in the flat. He sure picked the wrong school to visit that day!
