Ingredients You’ll Need

• 14 oz or 4 long stalks rhubarb
• 3 large eggs
• ¾ cup unsalted butter, cubed
• 3 teaspoons cornstarch
• ¾ cup granulated sugar
• A drop of pink food coloring, optional

Ingredient Notes

Look for bright red or deep pink rhubarb stalks for the prettiest color. The redder the stalks, the more vibrant your curd will be. Avoid stalks that are limp or have brown spots.

Unsalted butter gives you control over the saltiness. The butter adds richness and helps create that signature silky texture. Make sure it’s cubed so it melts evenly into the mixture.

Cornstarch acts as a thickening agent and helps prevent the eggs from curdling. Don’t skip it or substitute with flour, which will make the curd gummy. The food coloring is optional but helps restore the vibrant pink that fades during cooking.

Step-by-Step Instructions

Step 1: Process the Rhubarb

Wash and cut rhubarb into 2-inch pieces. Process in a food processor until it becomes a pulp. Push the pulp through a fine sieve to extract all the juice, then discard the fibrous pulp.

Step 2: Mix the Base

In a food processor or mixing bowl, combine eggs, sugar, and cornstarch. Blend or whisk until smooth with no lumps remaining. This creates a homogenous base that will thicken evenly.

Step 3: Combine and Cook

In a saucepan, combine 1 cup of rhubarb juice, the egg mixture, and cubed butter. Set over low heat and whisk constantly as the butter melts and the curd begins to thicken.

Step 4: Stir Until Thickened

Continue cooking and whisking over low heat. Don’t rush by turning up the heat or the eggs will scramble. The curd is ready when it reaches the consistency of thick sour cream, about 15 to 20 minutes.

Step 5: Strain and Flavor

Remove from heat and push through a fine sieve again for silky smoothness. Stir in the remaining rhubarb juice to boost tartness and add a drop of pink food coloring if desired.

Step 6: Chill and Store

Transfer to clean jars and refrigerate for at least 3 hours or overnight. The curd will thicken further as it chills. Store covered in the fridge for up to one week.

Pro Tips & Cooking Hacks

• Always cook over low heat to prevent curdling and lumps
• Whisk constantly the entire time for smooth, creamy texture
• Save some rhubarb juice to adjust tartness at the end
• Strain twice for the silkiest possible curd
• Taste before chilling and adjust sweetness if needed

Tips & Variations

Add a teaspoon of vanilla extract or almond extract for extra depth. Grated ginger or orange zest also pair beautifully with rhubarb’s tartness.

For a less tart curd, increase the sugar by 2 to 4 tablespoons. You can also blend rhubarb with strawberries for a sweeter, more complex flavor.

Make a larger batch and freeze portions in small jars. The curd freezes well for up to three months. Thaw overnight in the fridge before using.

Serving Suggestions

Spread rhubarb curd on warm scones, toast, or English muffins for a delicious breakfast treat. It’s also fantastic dolloped on pancakes, waffles, or French toast.

Use it as a cake filling between vanilla or almond cake layers. The tartness cuts through sweet frosting beautifully. It’s also stunning swirled into cheesecake or layered in parfaits.

Stir a spoonful into plain yogurt or oatmeal for a bright, tangy flavor boost. It transforms simple breakfast staples into something special.

Common Mistakes

• Cooking over high heat causes curdling and lumpy texture
• Not whisking constantly leads to uneven thickening
• Skipping the sieve step leaves fibrous bits in the curd
• Using green rhubarb results in less vibrant color
• Not chilling long enough means runny, not-fully-set curd

What to Serve With Rhubarb Curd

Rhubarb curd shines at brunch spreads alongside fresh pastries, croissants, and muffins. Pair with clotted cream or mascarpone for an indulgent treat.

It’s perfect for afternoon tea service with shortbread cookies, madeleines, or butter cookies. The tartness provides a refreshing contrast to sweet baked goods.

Use it as a dessert topping for vanilla ice cream, pound cake, or angel food cake. A small spoonful goes a long way in adding bright, complex flavor.

Frequently Asked Questions

Can I use frozen rhubarb for this recipe?

Yes, frozen rhubarb works well. Thaw it completely and drain excess liquid before processing. You may need slightly less sugar since frozen rhubarb can be sweeter.

How do I prevent the curd from curdling?

Always use low heat and whisk constantly. Never let the mixture boil. The cornstarch helps stabilize the eggs and prevents curdling.

Why did my curd lose its pink color?

Rhubarb naturally loses some color when cooked. Adding a tiny drop of food coloring restores the vibrant pink. This is purely for aesthetics and totally optional.

Can I reduce the sugar in this recipe?

You can reduce it slightly, but rhubarb is very tart. The sugar balances the acidity and helps with preservation. Start with the full amount and adjust next time.

How long does rhubarb curd keep?

Store in the refrigerator for up to one week in clean, airtight containers. You can also freeze it for up to three months in freezer-safe jars.
