Why This Recipe Works

Combining rhubarb and lemon creates a depth of flavor rarely attempted in pies. I developed this recipe after struggling to balance rhubarb’s natural acidity and lemon’s intense brightness. The cardamom adds warmth, while the wheat flour in the crust prevents a dry, crumbly texture.

The custard layer acts as a barrier between rhubarb and crust, preserving the base’s crispness. By cooling the compote before assembly, I avoid soggy crusts while letting the spices infuse the filling through the baking process.

Chef Tips for Perfect Results

• Use a digital kitchen scale for accurate dry ingredient measurements
• Chill custard in refrigerator for 6+ hours for cleaner slices
• Tap filled crust gently before baking to release air bubbles
• For crisper crusts, chill assembled pie for 30 minutes before baking
• Measure fresh lemons directly using 14-16 halves = 2/3 cup juice

Nutritional Information

Frequently Asked Questions

Can I substitute almond flour in the crust?

No, almond flour melts rather than baking, causing collapse. Use walnuts finely chopped instead for texture

How to test doneness without overbaking?

The center should jolt slightly when shaken. Visible bubbles on surface = fully set

Why is my crust cake-like?

Over-mixing, adding liquid gradually, or failing to keep butter cold increases gluten. Chill dough 1 hour minimum

Can I make this ahead of time?

Assembled pie stores 24 hours in fridge. Make crust + custard separately for up to 2 days

What to serve with leftover slices?

Pair with Chantilly cream and candied orange peels for evening dessert platters

Instructions

In a food processor, combine all-purpose flour, wheat flour, sugar, and a pinch of salt. Pulse to mix.
Add cold butter and pulse until a coarse, rice-like texture forms.
Whisk egg yolk and milk together in a small bowl. With the processor running, add the liquid mixture until the dough comes together.
Press the dough into a 9-inch pie pan and chill for 1 hour.
Preheat oven to 400°F (200°C). Toss rhubarb with 1/3 cup sugar, vanilla paste, and cardamom.
Spread the rhubarb in a single layer on a baking sheet. Cover loosely and bake for 20 minutes. Remove the cover and bake an additional 10-15 minutes, until tender. Let cool.
Preheat oven to 375°F (190°C). Blind bake the chilled crust: Line with parchment and fill with pie weights or dried beans. Bake covered for 10 minutes, then uncover and bake for 5 minutes more.
In a blender, mix custard: Combine sugar, yogurt, egg, lemon zest, and 2/3 cup lemon juice. Blend until smooth.
Spread cooled rhubarb compote into the partially baked crust. Pour the custard mixture over the rhubarb, just below the rim.
Bake for 25 minutes, or until the edges are set but the center still jiggles slightly. Cool completely before chilling or serving.

Notes

Chill crust for at least an hour before baking to prevent shrinkage.
Use fresh lemon juice for the brightest flavor.
Chill custard in the refrigerator for 1-2 hours to ensure it sets properly.
Use a 9-inch pie pan for consistent results.
For a nutty flavor, stir in 1 tbsp ground cinnamon with the rhubarb, if desired.
