Thanks all!
LOUIS - yes, you can freeze rhubarb and I think that's a great way to preserve it. When I get it home, I rinse it off, dry it, and then cut it into pieces about 1 inch long. Then I pack it up in freezer bags - about 4 cups per bag - and put it in the freezer. Because it is made up mostly of water (like celery) the freezing cellular structure of the rhubarb will be a bit broken from the freezing, so when you thaw it you will notice it is soft - and you'll need to drain in. But it is ready to use in pies, cobblers, breads, etc. and tastes great!
JOSHUA - good for you harvesting all that wonderful rhubarb! It will now go to good use ;-) It looks good and your freezer will be stocked!!
HANS - so far, I really love the Kelvinator! It's a bit of a plain-Jane model, but the burners all work well and the oven holds well and bakes evenly. I'm kind of a fan of those front knobs - no reaching over a hot stove!
