Rhubarb
How to Prepare Rhubarb for Cooking
Cut from the plant close to the root, cut off the leaves and wash thoroughly.
You do not have to peel rhubarb, however if the stalk is quite thick peeling the tougher exterior may be a good idea.
The fresh rhubarb can be chopped and refrigerated or frozen for future recipes.
Keep in mind, you can eat the green stalk however the leaves are poisonous to eat so discard them (for humans and animals alike).
