First things first: do not wash your rhubarb until you’re ready to use it. I know, I know—it looks dusty and a bit rude. But washing it early is like giving a sponge a bath and then throwing it in your crisper drawer. It becomes a soggy, sad mess.
Think of the stalk like a grumpy teenager. It does not want to be wet. It wants to be dry, a little cold, and left alone. If you treat it with that level of respect, it will reward you with perfect pies for weeks.
The Plastic Bag Tuck (A Classic Move)
This is the easiest trick in the book, and it’s almost too simple. Take your unwashed rhubarb stalks and wrap them in a slightly damp paper towel—slightly damp, not dripping. Then, slide the bundle into a plastic bag, but don’t seal it shut.
You want it to breathe, like a sleeping dragon with its mouth open just a crack. Leave a little gap for air to escape, or you’ll create a miniature swamp inside your fridge. No one wants swamp-rhubarb.
Stick it in the crisper drawer (the vegetable VIP lounge) and it will stay fresh for about two to three weeks. It’s almost magical. You’ll forget about it, then find it and feel like a brilliant grocery hero.
