There are liners for crockpots? What are they made of? Where do you get them? Would aluminum foil do the same thing? (Please excuse—lotsa errands yesterday so am just catching up.)
Reynolds makes crockpot liners. Made of the same stuff as the baking bags. They are usually on a top shelf, because not too many folks know about them. If you don’t see them, ask for them.
I have used them for years, but the Walmart I go to either doesn’t carry them, or they fly off the shelves. Just line the crock, put in your stuff and when you’re done cooking, gather the top and tie it and throw it out. Simple!
