Freezing Rhubarb – Steps on how to freeze rhubarb
If you grow rhubarb then you’ll want to know how to preserve it so you can use it all year long. Freezing it is a great way to preserve it.
What is rhubarb?
Rhubarb is a perennial plant that grows from rhizomes. The stalks of rhubarb are edible and are often red or green. Rhubarb stalks resemble celery in looks but taste entirely different. They have a very sour taste. The leaves contain high levels of oxalic acid and are inedible.
How do I harvest rhubarb?
I select a few stalks from each rhubarb plant to remove. I never take more than 1/4 of the plant at a time. You want your plant to continue producing and taking too many stalks may cause it to die.
Use a small knife and cut the stalk near the base of the plant.
Remove leaves and discard.
How do I prepare rhubarb for freezing?
- Rinse rhubarb
- Remove any loose strings
- Chop into 1/2″ chunks
- Place in a freezer safe bag and place in freezer
How do I use frozen rhubarb?
I use frozen rhubarb in any recipe calling for rhubarb. Many times I will add it frozen and increase the cooking time by 5-10 minutes. You can use frozen rhubarb in rhubarb muffins, rhubarb bread, rhubarb sauce and this delicious rhubarb crisp. It can also be used in a savory BBQ dish from House of Nash Eats.
Tips for freezing rhubarb
- Always label your freezer bag and add the date.
- Cut rhubarb to the size you will need for a recipe.
- Freeze in a freezer that does not have an automatic defrost.
- Use rhubarb within one year.
- If rhubarb freezes together, just gently break apart while still in bag.
- Freeze the amount you have on hand. Sometimes I have just a few cups to freeze and other times I may have several dozen cups.
