My leftover cranberry sauce goes into small glass containers (with plastic lids) and into the freezer. This year we finally used the last of three of those containers that were left over from four years ago! It was just as yummy as the first time we used it. Only Mom and I eat it here, so a little goes a long way and it's convenient not to have to make or buy it each year.
Leftover cranberry sauce is also good over vanilla ice cream, or even a fruit sherbet if you like the tart. You can also mix it in to
apple pie filling before you bake a pie for an interesting change of pace. It is really good combined with orange juice and/or zest in muffins and scones (in fact when I make my own cranberry sauce I use orange juice and zest in it.)
I'm not a big baked bean person, and on the rare occasions we have them my man eats them all up, so I've never had to deal with leftover baked beans. All I can think of off the top of my head is to slice and brown a good amount of kielbasa or some other kind of sausage with some onions, and mix them together with the baked beans and bake as a casserole, maybe with some kind of cheese (grated parmesan comes to mind) or bread crumb topping?
ORRRRRR...... harking back to the original
thread you pulled this from, you could add the baked beans to other leftover items, soups, stew, etc, and see what kind of new taste profile happens! (If you don't like it you can always
feed it to
chickens, or pigs if you have them.)
