I have an older crock pot, and the lid needs to be replaced. It's an odd size, and the only appropriate lid I could find has a tiny hole in it for venting. Will the crock pot still work normally if it's vented?
Yes, it will work with some tinkering. Many older crock pot lids had a flap which could be opened or closed to allow steam to vent if a recipe started out especially wet. If you don't want to dry out your food, I'd suggest wrapping the lid with aluminum foil first to keep the hole mostly covered, or plan to add additional liquid in the beginning to make up for moisture lost due to evaporation.
