We have (had!) a lot of asian eggplants to preserve. Also cherry tomatoes, onions, garlic, peppers, zucchini, basil and
mushrooms.
At first I thought I'd make a big pot of ratatouille and then pressure-can it all. It would have come to 12 pints. What a palaver! What a mess!
Then I checked out how to dehydrate all the ingredients. Asian eggplants they recommend blanching whole before slicing 1/4" thick. Tomatoes I cut in half and dry cut-side up.
Made short work of thin-slicing the zucchini with a mandolin. Mushrooms, sliced. garlic, peppers & onions chopped coarsely.
Laid out each ingredient on a separate tray of the dehydrator at 125 degrees F. The tomatoes took the longest. As each ingredient was dried, put it in a separate pint jar.
But then when it was all done, layered the dried ingredients in pint jars. Only 4 pints, and a lot less mess than pressure-canning!
Considering reconstituting as a test right away -- thinking I
should pour boiling water over them in a bowl so they just plump up, drain the excess water & save, then sautee the whole lot in olive oil, adding the excess water as needed.
Would do it, but we have a few tubs of ratatouille from vege harvested earlier in the season, in the freezer!!
