Where to Buy Rhubarb

You can buy rhubarb at the Farmer’s market if it grows in your area. Rhubarb can also be found in the produce section of some grocery stores.

Don’t be afraid to buy stems with a green tinge to them. Different varieties of rhubarb will have different shades of red. Look for stems that are around 3/4″ in diameter and at least 7″ long.

If you can’t find fresh rhubarb you might be able to find frozen rhubarb in the frozen section of the grocery store.

Eating Raw Rhubarb

Yes, you can even eat rhubarb raw….just remember that it’s quite tart. However, dipped in sugar or another sweetener it makes a tasty snack.

When people talk about eating rhubarb they are talking about eating just the rib or stem of the rhubarb plant. Not the green leaf. The leaves are toxic and can cause all kinds of trouble for you. You can learn about the toxicity of rhubarb leaves in the article from Oregon State University. The leaves can be added to your compost.

How to Prepare Rhubarb for Preserving

Here’s how to prepare rhubarb for eating…

2. Cut the end of stems off and compost them
3. Remove any brown spots or tough strings with a vegetable peeler or knife
4. Rinse the rhubarb stalks in cold water
5. Slice the stalks crosswise into 1-2″ sections. Rhubarb cooks down quite a bit so usually isn’t cut into super small pieces
