I forgot to update when this happened, but a few weeks ago I managed to stuff everything from the chest freezer into the fridge freezer and UNPLUG!!! I danced around the kitchen and my husband laughed at me. Then he got irritated for a few days when things jumped out of the freezer at him every time he opened it. :) But we ate some more down so that problem has been solved. In fact, it's now only about half full.
To get rid of our halibut, and as an excuse to see friends here before we leave (next week already!), we threw a little party and cooked up some beer battered halibut. Best part: it used homebrew, halibut, and some of our flour and spices. Didn't have to buy anything except some vegetables for a side and lard to fry in. Husband told me it was some of the best halibut he'd ever had. We also gave away two more giant salmon fillets to a friend.
We've been cooking up so much freezer-burned salmon for the dog that she actually walked away from her bowl the other morning, all droopy-eared and sad, like, "Oh, it's salmon again." She got about four steps away, then perked up again and rushed back to the bowl. I could practically hear her thinking, "Wait, what am I talking about? It's salmon!!!"
We still have a bunch of chicken broth to use up, but it's far too hot to make soup. (Upper 80s in Fairbanks in May? Holy hell.) Also have some frozen peas to use up, but that should be easy enough.
Even if we don't use it all up, what we've got frozen should be easy enough to take with us, at least as far as my in-laws' house.
Wheee!! I still can't believe how much progress we made on this, and a lot of it is due to the support and inspiration I found in this thread. Thank you all!
