Can You Freeze Rhubarb?

Can you freeze rhubarb?

Yes, rhubarb freezes excellently and is one of the easier fruits/vegetables to freeze. Note that botanically rhubarb is a vegetable, but it's used culinarily as a fruit due to its tart flavor and pairing with sugar in desserts. The high acidity (pH 3.1-3.3) acts as a natural preservative; blanching is not needed; the texture changes that occur during freezing don't matter because rhubarb is always cooked. All varieties freeze well: red rhubarb (most common, deep red color); green rhubarb (pale or green stalks, equally edible); pink champagne rhubarb; Victoria rhubarb; cherry red varieties. Important safety note: rhubarb leaves contain high levels of oxalic acid and are toxic - always remove and discard the leaves before cooking or freezing; only the stalks (petioles) are edible. Frozen rhubarb lasts 8-12 months for best quality at 0°F (-18°C); safe indefinitely.

How do you freeze rhubarb?

Simple methods work for rhubarb. Method 1: chopped (most useful). Wash rhubarb stalks; trim off the leaves completely (discard - toxic); trim off the leaf base; cut stalks into 1/2 to 1-inch pieces; spread on a parchment-lined baking sheet in single layer; flash freeze 1-2 hours until solid; transfer to labeled freezer bags. Method 2: pre-portioned for pies. Bag rhubarb in 4-cup portions (the standard amount for a 9-inch pie); makes pie-making convenient. Method 3: sugar-pack. Mix 1 cup sugar per quart of chopped rhubarb; the sugar coating protects color and provides preservative effect; pack into freezer bags or containers; great for fruit pies. Method 4: rhubarb sauce or compote. Cook rhubarb with sugar until softened (10-15 minutes); cool; portion into freezer containers. Label everything with date and quantity.

How do you use frozen rhubarb?

Frozen rhubarb is most often used directly from the freezer. For pies and crisps: add frozen chopped rhubarb directly to fruit pie filling with sugar, flour or cornstarch, and lemon juice; bake at 375°F for 60-70 minutes. The flour or cornstarch absorbs the excess juice from the frozen rhubarb. For strawberry-rhubarb pie (the classic): mix frozen strawberries and rhubarb in equal parts; add sugar, lemon juice, and cornstarch; bake. For rhubarb crumble or crisp: combine frozen rhubarb with sugar and a topping of oats, butter, and sugar; bake until bubbly. For rhubarb compote: combine frozen rhubarb with sugar and water; cook 10-15 minutes until softened. For rhubarb chutney: combine with vinegar, sugar, raisins, and spices. For rhubarb jam: cook with sugar and lemon juice; can or refrigerate. Refrigerator thawing if needed: 4-6 hours; drain excess liquid; use immediately.
