Actual food hack: Save vegetable trimmings in a bag in the freezer. Onion skins, carrot peelings, celery bits, broccoli stems, etc. When it's full, put them in a pot and cover with water and cook at medium heat for a couple hours to make free vegetable broth.
Agree to disagree, I've ruined more than one broccoli cheddar soup trusting a stem has softened enough when it's almost as cheap, and sometimes cheaper, to just get the florets.
I remember reading some kind of tip, maybe making a sauce out of onion and garlic skin, but in any case, is there any concern with mold or food safety with this method? There was some talk of it with whatever I read.
If you're freezing it all, no. It could get freezer burned but that just makes it taste off it should still be safe to eat. If you keep stuff in the fridge not freezer, or you let things sit on the counter too long between each processing step, it could go bad. That's just general food safety though not just a trimmings thing
Well, that's the thing, who washes onion skins? Unless you're going to use them later. But even then, dirt tends to get stuck between the outer layers.
i love it, but the "bag" to which you refer, is a plastic bag. the freezer? that you bought at a big box store? or say you bought second hand? that all requires massive amounts of infrastructure. Massive amounts of power. Massive engineering projects to bring you that power.
you're not a hippy just because you store veggies in the freezer.
