• 2 to 4 tbsp cold water

How to Make It

Start by preparing the tart crust and filling.

Make the crust

In a large bowl, combine the flour, butter, and sugar. Use a pastry cutter or your fingers to mix until crumbly. Stir in the egg yolk and gradually add cold water until the dough holds together.

Chill the dough

Wrap the dough in plastic wrap and refrigerate for at least 30 minutes. This helps the butter firm up for a flakier crust.

Preheat the oven

While the dough chills, preheat your oven to 375°F (190°C). This ensures that the crust bakes evenly.

Roll out the dough

On a floured surface, roll out the chilled dough into a circle about ¼ inch thick. Carefully transfer it to a 9-inch tart pan, pressing it into the edges. Trim the excess, and prick the bottom with a fork.

Par-bake the crust

Line the crust with parchment paper and fill it with pie weights or dried beans. Bake for 15 minutes, then remove the weights and parchment paper. Bake for an additional 10 minutes until lightly golden.

Prepare the filling

In a bowl, combine the chopped rhubarb and sugar, mixing well. In another bowl, whisk together the eggs, cream, and vanilla. Gradually pour the egg mixture into the rhubarb, mixing gently.

Fill the tart

Pour the rhubarb custard filling into the pre-baked crust, spreading it evenly across the surface.

Bake the tart

Bake the tart for 30-35 minutes, or until the filling is set but still slightly jiggly in the center. Let it cool completely before serving.

How to Store It

Fridge: Store in an airtight container for up to 3 days.
Freezer: No, it doesn’t freeze well due to the custard.
Reheat: Warm in the oven at 350°F (175°C) for 10 minutes.

Tips for Best Results

• Use fresh rhubarb for the best flavor and texture.
• Allow the tart to cool completely before cutting to set the filling.
• If using frozen rhubarb, thaw and drain excess moisture before using.

Serving Suggestions

• Serve with a dollop of whipped cream on top.
• Pair with vanilla ice cream for an indulgent treat.
• Enjoy alongside a cup of tea or coffee for a cozy afternoon snack.
