The History of Rhubarb and Custard: A Classic British Pairing
The pairing of rhubarb and custard has deep roots in British culinary history. Rhubarb was introduced into English cuisine in the 18th century, prized initially for its medicinal properties before becoming a favored ingredient in desserts. Custard, a creamy egg and milk-based concoction, has been enjoyed since medieval times.
The marriage of these two elements — the sharpness of rhubarb and the sweetness of custard — became a staple in British homes and bakeries, especially in spring and early summer when rhubarb is at its best. Today, Rhubarb and Custard Tart continues to be a beloved dessert, celebrated for its perfect balance of flavors and textures.
Understanding the Star Ingredients
Rhubarb: The Tart Marvel
Rhubarb is technically a vegetable but is treated like a fruit in cooking due to its tart flavor and culinary use. Its pink to deep red stalks bring vibrant color and a refreshing tang to desserts. Known for its unique sourness, rhubarb provides a palate-cleansing counterpoint to rich custards and creamy fillings.
Why rhubarb works so well in custard tarts:
- Its acidity cuts through the sweetness, preventing the dessert from feeling cloying.
- It adds a fresh, spring-like brightness.
- The soft texture when cooked pairs beautifully with smooth custard.
Custard: Creamy and Comforting
Custard is traditionally made by gently cooking eggs, milk or cream, sugar, and flavorings such as vanilla. It has a silky, creamy texture and a sweet flavor that complements many fruits and pastries.
Types of custard used in tarts:
- Baked custard: Thickens in the oven as it bakes inside the tart shell.
- Stovetop custard: Cooked on the stove, then poured into the pastry before baking or chilling.
The custard in a Rhubarb and Custard Tart acts as a creamy cushion for the tangy rhubarb, creating a harmonious flavor balance.

Step-by-Step Recipe: How to Make Rhubarb and Custard Tart
Step 1: Make the Pastry Dough
- Combine dry ingredients: In a bowl, sift together flour, powdered sugar, and salt.
- Cut in the butter: Add cold butter cubes and use fingertips or a pastry blender to work the butter into the flour until the texture resembles breadcrumbs.
- Add egg yolk and water: Mix in the egg yolk, then slowly add cold water, one tablespoon at a time, until dough forms.
- Chill: Wrap dough in plastic wrap and refrigerate for at least 30 minutes to rest and firm up.
Step 2: Blind Bake the Tart Shell
- Preheat oven: Set oven to 180°C (350°F).
- Roll out dough: Lightly flour surface and roll dough to fit a 9-inch tart pan.
- Line tart pan: Gently press dough into pan, trimming edges.
- Add weights: Line with parchment paper and fill with baking beans or rice.
- Bake: Bake for 15 minutes, then remove weights and bake for 5–7 minutes more until golden.
- Cool slightly: Let the shell cool before filling.

Step 3: Prepare the Rhubarb Filling
- Mix rhubarb and sugar: Toss rhubarb pieces with sugar in a bowl. If using strawberries, add them here.
- Cook slightly (optional): Simmer gently for 5 minutes to soften and reduce tartness. Cool before adding to tart.
Step 4: Make the Custard
- Whisk eggs and sugar: Beat eggs and sugar in a bowl until pale and creamy.
- Add cornstarch: Stir in cornstarch for extra thickening, if desired.
- Heat milk and cream: Warm milk and cream in a saucepan over medium heat until just simmering.
- Temper eggs: Slowly pour some warm milk mixture into egg mixture, whisking continuously to avoid curdling.
- Combine and thicken: Return mixture to saucepan and cook on low heat, stirring constantly until custard thickens. Remove from heat and add vanilla extract.
Step 5: Assemble the Tart
- Add rhubarb: Spread rhubarb and strawberries evenly in the pastry shell.
- Pour custard: Carefully pour custard over fruit.
- Bake: Bake at 180°C (350°F) for 25-30 minutes, until custard is set but slightly wobbly.
- Cool: Allow tart to cool before slicing.
Variation: Rhubarb Custard Pie With Meringue
For a show-stopping finish, top your tart with a light meringue.
- Make meringue: Whisk egg whites until soft peaks form, gradually adding caster sugar until stiff peaks form.
- Top tart: Spread meringue over warm custard tart.
- Bake again: Place under a hot grill or in the oven at 220°C (425°F) for 3-5 minutes until meringue is golden.
This classic Rhubarb Custard Pie With Meringue adds a fluffy, sweet topping that contrasts wonderfully with the tart rhubarb and creamy custard.
Why Add Strawberries? The Rhubarb Strawberry Tart and Strawberry Rhubarb Custard Dessert
Adding strawberries to your rhubarb tart adds a natural sweetness and extra juiciness, rounding out the tart’s flavor profile. The combination is a classic in the world of Rhubarb Desserts and especially shines in a Strawberry Rhubarb Custard Dessert or Strawberry And Custard Tart.
Fresh strawberries bring:
- Bright red color for visual appeal.
- Sweetness that complements the tangy rhubarb.
- Juicy texture that melds with creamy custard.
If you prefer a more pronounced strawberry flavor, increase the strawberry quantity or brush the finished tart with strawberry glaze.
Tips for Perfecting Your Rhubarb and Custard Tart
Use Fresh, Seasonal Rhubarb
The best rhubarb comes in spring and early summer. Look for firm, bright stalks with a deep red color for the sweetest flavor.
Adjust Sugar to Taste
Rhubarb’s tartness can vary. Taste your fruit before baking and adjust sugar accordingly to avoid an overly sour tart.
Blind Bake for a Crisp Crust
Always blind bake the tart shell to prevent a soggy bottom caused by moist custard and fruit.
Temper Your Eggs
Slowly combine hot milk with eggs to avoid scrambling and achieve a smooth custard.
Don’t Overbake
Custard should be just set, with a slight wobble in the center. Overbaking causes curdling and dryness.
Cool Properly
Allow the tart to cool completely for clean slicing and perfect texture.
