Jo Ann, put left over sauces in jelly jars to vacuum seal to keep in the fridge/freezer. A jelly jar should fit in a large mouth canning jar, to use as a canister, to seal the small jar. I save as many small jars as possible to do just as you want to do. If you find smaller baby food jars, you might be able to stack 2 in the quart jar to seal both at the same time.
