does rhubarb keep longer in the refrigerator?
Wash and cut all of the leaf away from the rhubarb and it will keep well in the refrigerator for two to three weeks, either wrapped in aluminum foil or in sealed plastic bags
A large skillet with a lid, or a large (8-10 qt.) stock pot with a lid, like you cook beans in A crock pot, or slow cooker, is also something you could use, depending on what you're cooking.
It will depend on what you are making a Pyrex casserole dish will do, but they are not stove top friendlyA roasting dish and tinfoil would be a last resort.
