If it turns out there's no place that can take your extra food -- a strong possibility, since many have rules about the type and quantities they can accept -- then amazingrace's advice is the next best thing. Just don't make so much of the new things. And see if there's some way you can con your family into eating new things.
I think it's a shame when people are "picky" -- it means two things: 1) that they have closed minds as well as closed taste buds, and 2) someone has been letting them get away with it for much too long. I was raised by parents who were adolescents during the Depression, and there was no question in our house: eat what you're offered, or don't eat. If something turned out to be horrible (like the meatballs in a sauce of grape jelly and chili sauce that EVERYONE hated), we still ate it until it was gone, and then it was never made again. But we would never ever throw out edible food.
I still can't, so Ed Buchanan's advice is next best: Turn what you've made into something else that your family will eat: If they like filled pastas such as ravioli, mush together whatever you have and use it for that. (This works better than it sounds.
) Or into soup, or some other dish. Rinse off the sauce (sigh) and add the solids to a different sauce.
"Repurposing" food can work better than you'd imagine. I find that I can't make beef braciole now unless I have leftover meat loaf for the filling.
Ooh, I do have some in the freezer! Just gotta go get some round steak now!
