I make veggie/bone broth. I use all my veggies trimmings, tops, peals, lettuce, spinach, cabbage or veggies that are going bad before getting eaten. Throw in freezer gallons bags and save and add to my bone carcass. Always a a bit if vinegars to pull collagen out of bone. Just enough water to cover and simmer in crockpot for 24 to 48 hours. Strain thru cheesecloth, chill and remove grease. It’s the thickest gelatin broth you will have. Amazing flavor delicious!!!!if you put in dark paper skin from onions you broth will be a dark rich color! Amazing flavor from all scraps!!!!!oh don’t oversalt. I have used my insta pot but prefer my 8 gt crockpot!Stock is so rich you can dilute
