Preserving Rhubarb for Later Use

Rhubarb, a perennial vegetable known for its tart taste and vibrant red stalks, can be preserved to enjoy its unique flavor long after its growing season. Preserving rhubarb not only allows you to savor its distinct taste during the off-season but also helps reduce food waste. There are several methods you can use to preserve rhubarb, each offering its own benefits and culinary applications.

Freezing Rhubarb

Freezing is one of the simplest and most popular methods for preserving rhubarb. Follow these steps to freeze rhubarb:

Wash the rhubarb stalks thoroughly under cold water and remove any leaves, as they are toxic.

Cut the stalks into desired lengths, typically 1 to 2-inch pieces.

Blanch the rhubarb by placing the pieces in boiling water for 1 to 2 minutes, then immediately transfer them to an ice bath to cool rapidly.

Drain the blanched rhubarb and pat dry with a clean towel.

Place the rhubarb pieces in airtight freezer bags or containers, removing as much air as possible.

Label the bags or containers with the date and store them in the freezer.

Frozen rhubarb can be used in various recipes, such as pies, jams, sauces, and compotes. However, keep in mind that freezing can slightly alter the texture of rhubarb, making it softer. Therefore, it is best suited for cooked or baked dishes.

Canning Rhubarb

Canning is another popular method for preserving rhubarb, allowing you to enjoy its flavor and texture similar to fresh rhubarb. Here’s how you can can rhubarb:

Wash the rhubarb stalks thoroughly under cold water and remove any leaves.

Cut the stalks into desired lengths, typically 1 to 2-inch pieces.

Prepare a simple syrup by combining water and sugar in a saucepan and heating until the sugar dissolves.

Blanch the rhubarb by placing the pieces in boiling water for 1 to 2 minutes, then immediately transfer them to an ice bath to cool rapidly.

Drain the blanched rhubarb and pack it tightly into sterilized canning jars, leaving a 1/2-inch headspace.

Pour the prepared syrup over the rhubarb, leaving a 1/2-inch headspace.

Remove any air bubbles by gently tapping the jars and adjust the headspace if necessary.

Wipe the jar rims clean, place the lids and rings on the jars, and tighten until fingertip tight.

Process the jars in a boiling water bath for the recommended time based on your altitude and jar size.

Remove the jars from the water bath and let them cool on a towel-lined countertop.

Check the seals, label the jars with the date, and store them in a cool, dark place.

Dehydrating Rhubarb

Dehydrating rhubarb is an excellent method for preserving it in a concentrated form, perfect for snacking or adding to various dishes. Here’s how you can dehydrate rhubarb:

Wash the rhubarb stalks thoroughly under cold water and remove any leaves.

Cut the stalks into thin slices, approximately 1/4-inch thick.

Blanch the rhubarb by placing the slices in boiling water for 1 to 2 minutes, then immediately transfer them to an ice bath to cool rapidly.

Drain the blanched rhubarb and pat dry with a clean towel.

Arrange the rhubarb slices in a single layer on dehydrator trays, ensuring they do not overlap.

Set the dehydrator to a temperature of around 135°F (57°C) and let it run for 8 to 12 hours, or until the rhubarb slices are completely dry and brittle.

Once dried, let the rhubarb slices cool to room temperature.

Store the dehydrated rhubarb in airtight containers or resealable bags, away from moisture and light.
