Armed with my trusty apple peeler (which peels, cores, and slices all in one fell swoop)...
...I turned most of them into apple sauce. I used Tammie's idea of flavoured sauces, adding fruit and spices to make three different batches.
The end result was 5 pints each of Strawberry, Blueberry, and Spiced Apple sauce. The kids gave them a big thumbs up. They're a bit more rustic than some sauces, as I didn't remove the berry seeds and stray bits of peel with a food mill. Instead I used my immersion blender to incorporate them into the sauce (I kind of like that little bit of texture).
I also froze a bunch of the apples, unpeeled but cored and sliced, and sealed them in pairs with my Foodsaver (I scored a huge box of generic vacuum sealer bags on Freecycle yesterday!). Each apple is approximately 2 cups, which is just the right amount for my favorite apple muffin recipe.
I ended up with a mountain of apple skins and cores after all this. Hating to throw them all in the compost, I started a batch of the apple wine that Tammie talked about recently (she seems to be my apple idea connection!). It turns out she had the same thought and is making a similar batch. I'm hoping that the seeds don't impart a bad flavour to the final product - we should know in about a month.
