Dehydrating rhubarbย allows you to preserve it for year-round use in a variety of backpacking meals including oatmeal, desserts, stews and baked goods.
How to dehydrate rhubarb
Step 1 – selecting rhubarb
Choose fresh, firm stalks that are vibrant in color and free from blemishes or signs of decay.
Step 2 – cleaning&trimming
Thoroughly wash the rhubarb stalks under running water to remove any dirt or debris. Remove and discard all rhubarb leaves, as they are toxic.
Trim the ends of the stalks.
Step 3 – cutting
Slice the stalks into uniform pieces, approximately 1/4 to 1/2 inch thick. Uniformity ensures even drying.
Step 4 –ย blanching or steaming
This procedure will help to eliminate acidity in the stalks and will make the rehydration process easier.Steam the rhubarb until slightly tender.
How to steam:
- Fill a pot with about 1-2 inches of water. Bring water to a boil.
- Place a steamer basket or colander over the pot with boiling water, making sure it does not touch the water.
- Cover with a lid and steam for 3-5 minutes, or until the rhubarb is tender but not mushy.
- Carefully take the rhubarb out of the steamer and let it cool slightly before drying.
Step 5 – arrangement
Place the rhubarb pieces in a single layer on dehydrator mesh sheets ensuring they do not overlapย
Step 6 – drying process
Set the dehydrator to 130ยฐF (54ยฐC). Dry for 8-14 hours, or until the pieces are crisp and brittle. Drying times may vary based on humidity and the thickness of the pieces.
Regularly check the rhubarb during the drying process to prevent over-drying, which can lead to a loss of flavor.
Step 7 – making rhubarb powder (optional)
Grind dehydrated rhubarb into a fine powder using a coffee grinder.
This powder can be sprinkled over oatmeal, incorporated into sauces, or mixed with sea salt to create a unique rub for meats and fish.
Storage tips
- Once completely cooled, store the dehydrated rhubarb in airtight containers, such as glass jars or vacuum-sealed bags.
- Keep the containers in a cool, dark place away from direct sunlight to maximize shelf life.
- Properly stored, dehydrated rhubarb can last up to a year.
