I've put cooked dried beans into my compost. When I next looked into the Bio-Stack, there were no traces of the beans--a mixture of kidney beans and pink beans, I think--or
their cooking liquid.
Granted, they weren't pickled, but they were
cooked. My original plan, to make chili, was delayed, then I forgot about the beans...until they became a science experiment in the fridge! DH wanted to throw them out
! (silly man; he's lived with me how long?! and wanted to throw them into the garbage?!?!?!
) I said, No; just put them into the compost--here's a spatula to be sure it all goes into the compost. I don't want it back....
While I continued to look for any other science experiments that might have gotten away from me during a particularly intense patch of work/dog care this fall (lost another doggie, as readers of my sig have noticed
I've also put cooked rice, every now and then, into the compost. But that was a l-o-n-g time ago, before we had dogs. Now, if there's left-over rice, we have fourfoots to help out!
Other cooked items
that've made it into the Bio-Stack.... I'm just trying to remember what-all may have gone to feed compost rather than us in the approx. 25+ years that I've had the bin and I've been cooking, gardening, etc.
--the beans (not just the would-be chili beans, but refritos gone bad)
--skin from cooked pumpkin (and cooked pumpkin that went bad in the fridge)
--skin from blanched stone fruit, e.g., nectarines and peaches
--stale or molded bread (it was already baked when we brought it home)
--canned tomato paste (salt-free...)
--corn cobs (left-overs from eating cooked corn on the cob)
Quite a variety! With no ill effects to my compost. In fact, I would have wasted a lot of food without the compost pile. ("Waste" in this sense meaning "of no use to anyone.") If DH and I or the dogs or even the cats can't eat the food in its current form, the "compost critters" definitely can; later, that compost will help us grow new berries, veggies, and leafy greens, including herbs.
It's extremely rare that I need to actually throw out foodstuffs--although if something (e.g., flour) has become infested with crawly things, it's transferred immediately into double plastic bags and walked to the outdoor compost. It doesn't sit around waiting for the next "compost run."
Foodstuffs that hit the garbage can are cooked chicken/turkey/meat bones. Cheeses that get away from us. The fats from meat that either cook out into the pan or can be cut off with a knife are deposited into a glass jar with a lid; when the jar is full or almost full, it goes into the garbage. This helps prevent clogged plumbing! (Yes; household tips are an additional benefit here at THG.
I hope my experience helps others relax about putting cooked items into their compost piles, bins, heaps, etc.
