I have a lot of rhubarb. I have 12 plants. Several hundred (probably close to 500) stalks have been been pulled, and you can't tell that any have been taken.
My neighbor gave me a great idea on how to use it in large quantities: juice. I have access to a steam juicer, so I tried it. Now I have 20 or so pints of rhubarb juice in my freezer. It tastes awful by itself, but I mix it with apple or home-canned grape juice, and it tastes great!
