Rhubarb Curd
- Total Time: 40 minutes
Description
Rhubarb curd transforms tart spring stalks into a silky, pink spread that rivals lemon curd. This creamy, tangy treat works on everything from toast to cake layers.
Ingredients
400g (4 long stalks) fresh rhubarb, washed and cut into 2-inch pieces
3 large eggs
170g (3/4 cup) unsalted butter, cubed
3 teaspoons cornstarch
150g (3/4 cup) granulated sugar
A drop of pink food coloring (optional)
Instructions
1. Process the rhubarb pieces in a food processor until they turn into complete pulp. Push the pulp through a fine sieve with a spoon, extracting all the juice. You should get about 300ml (1 1/4 cups) of juice. Discard the fibrous pulp.
2. Combine eggs, sugar, and cornstarch in the food processor. Blend until completely smooth with no lumps remaining.
3. Combine 1 cup of rhubarb juice, the egg mixture, and cubed butter in a saucepan. Set over low heat and whisk constantly.
4. Keep stirring with your whisk until the butter melts completely and the mixture thickens to thick sour cream consistency. This takes about 15-20 minutes of gentle cooking.
5. Remove from heat and push the curd through a fine sieve again. This ensures no lumps and creates silky texture.
6. Stir in the remaining rhubarb juice for extra tart flavor. Add a drop of pink food coloring if you want to restore the vibrant color. Pour into clean jars and refrigerate for at least 3 hours or overnight until fully set.
Notes
Never raise the heat – high heat will scramble your eggs and create lumps. Low and slow is the only way.
Stir constantly and don’t stop whisking. Constant movement prevents the eggs from cooking unevenly.
Use the reddest rhubarb stalks you can find for the prettiest pink color. Green stalks taste the same but won’t give that gorgeous hue.
The curd thickens more when cold, so don’t panic if it seems thin in the pan.
Add a tiny splash of vanilla extract at the end for subtle depth that rounds out the tartness.

How To Make Rhubarb Curd
Step 1: Extract the Rhubarb Juice
Process the rhubarb pieces in a food processor until they turn into a complete pulp. Push the pulp through a fine sieve with a spoon, extracting all the juice. You should get about 300ml (1 1/4 cups) of gorgeous pink juice. Discard the fibrous pulp.
Step 2: Blend the Base
In your food processor, combine eggs, sugar, and cornstarch. Blend until completely smooth with no lumps remaining. This step is crucial for a silky final product!
Step 3: Combine Everything
In a saucepan, combine 1 cup of rhubarb juice, the egg mixture, and cubed butter. Set over low heat and whisk constantly. Don’t even think about turning up the heat – patience is everything here!
Step 4: Cook Until Thickened
Keep stirring with your whisk until the butter melts completely and the mixture thickens to thick sour cream consistency. This takes about 15-20 minutes of gentle cooking. Your arm will get a workout, but it’s worth it!
Step 5: Strain for Silkiness
Remove from heat and push the curd through a fine sieve again. This ensures absolutely no lumps and creates that restaurant-quality silky texture.
Step 6: Adjust and Chill
Stir in the remaining rhubarb juice for extra tart flavor. Add a drop of pink food coloring if you want to restore the vibrant color lost during cooking. Pour into clean jars and refrigerate for at least 3 hours or overnight until fully set.
You Must Know

Pro Tips & Mistakes to Avoid
Pro tip: Use the reddest rhubarb stalks you can find for the prettiest pink color. Green stalks taste the same but won’t give that gorgeous hue.
Pro tip: Make a double batch. This curd disappears fast once people taste it, and you’ll regret not having more.
Mistake to avoid: Don’t skip the straining steps. They transform good curd into exceptional curd with that professional texture.
Mistake to avoid: Don’t use a reactive pan like aluminum. Stick with stainless steel or enameled cookware to avoid metallic flavors.
Flavor Variations
Strawberry rhubarb: Replace half the rhubarb with fresh strawberries. Blend both together for juice extraction.
Ginger rhubarb: Add 1 tablespoon freshly grated ginger to the rhubarb before processing. The spicy warmth is incredible.
Orange rhubarb: Add the zest of one orange to the egg mixture and use orange juice for part of the rhubarb juice.
Cardamom rhubarb: Infuse the rhubarb juice with 4-5 crushed cardamom pods while it’s warm. Strain them out before using.
Make-Ahead
Prep ahead: Extract the rhubarb juice up to 2 days in advance and store it in the fridge.
Full make-ahead: Curd actually tastes better the next day after the flavors meld. Make it 2-3 days before you need it.
Freezing: Freeze in airtight containers for 2-3 months. Thaw in the fridge overnight and stir well before using.
Serving Suggestions
On breakfast items: Spread on toast, English muffins, scones, or pancakes. Mix into yogurt or oatmeal for instant upgrade.
As dessert filling: Use between cake layers, in tart shells, or as a filling for thumbprint cookies. Swirl into cheesecake batter before baking.
Fancy applications: Dollop on pavlova, fill cream puffs, or layer in a trifle with whipped cream and berries.
How to Store
Refrigerator: Store in airtight jars for up to 1 week. Always use clean spoons to avoid introducing bacteria.
Freezer: Freeze for 2-3 months in freezer-safe containers. Leave 1/2 inch headspace as it expands when frozen.
Thawing: Thaw overnight in the fridge, never at room temperature. Stir well after thawing to restore creamy texture.

Dairy-free: Use vegan butter, but note the texture will be slightly different.
Gluten-free: Naturally gluten-free! Cornstarch is safe for celiac diets.
FAQs
Why did my curd turn out lumpy?
Either the heat was too high or you didn’t stir constantly. The eggs cooked too quickly and scrambled. Strain it through a fine mesh sieve to remove lumps.
Can I use frozen rhubarb?
Yes! Thaw completely and drain off excess liquid before processing. You might need slightly less rhubarb since frozen releases more water.
How do I know when it’s thick enough?
It should coat the back of a spoon and hold a line when you run your finger through it. Remember, it thickens more as it cools!
Why did my curd lose its pink color?
Heat naturally dulls rhubarb’s color. That’s why the optional food coloring helps restore the vibrant pink. It’s purely aesthetic – the flavor is perfect either way.
Can I double this recipe?
Absolutely! Use a larger saucepan and be extra vigilant about stirring. It might take a few minutes longer to thicken.
