I know this thread hasn't been active in a while, but I did a lot of preserving this year so I figured I'd list it here.
Peaches- the Medium sized peach tree in our yard went absolutely bonkers this year. I've made 4 different types of cobblers/buckles/bars, pure'd for peach Bellini's, frozen lots, eaten many, and given lots away.
Tomatoes- I know this is basically a lazy man's canning, but I've found that taking ~one dozen tomatoes and blanching, peeling, then plopping them in a ziploc bag and freezing to be super useful. We merely take these out of the freezer and then use them the same way you would canned tomatoes for making pasta sauces, but the flavor is so much better.
