For the Rhubarb Sauce:

4 cups chopped fresh rhubarb
1 cup granulated sugar
1/4 cup water

For the Shortbread Crust:

1 1/4 cups all-purpose flour
1/2 cup finely chopped pecans
1/2 cup cold unsalted butter, cubed
1/4 cup confectioners’ sugar
1/4 teaspoon salt

For the Rhubarb Curd Filling:

4 large egg yolks
3/4 cup granulated sugar
1/4 cup fresh lemon juice
1 tablespoon grated lemon zest
1/2 cup prepared rhubarb sauce
6 tablespoons unsalted butter, cubed
1 to 2 drops pink food coloring (optional)

For Garnish:

Confectioners’ sugar for dusting
Fresh rhubarb ribbons (optional)

Directions

Step 1: Prepare the Rhubarb Sauce

Preheat your oven to 350°F (175°C). In a large saucepan, combine the chopped rhubarb, sugar and water. Bring the mixture to a boil over medium heat. Reduce the heat and simmer while stirring occasionally until the rhubarb softens and the mixture thickens, about 10 minutes.

Allow the mixture to cool slightly, then transfer it to a food processor or blender. Blend until completely smooth. Set aside.

Step 2: Make the Shortbread Crust

In a food processor, combine the flour, pecans, butter, confectioners’ sugar and salt. Pulse until the mixture becomes crumbly but holds together when pressed between your fingers.

Press the dough evenly into the bottom and sides of an ungreased 9-inch tart pan with a removable bottom.

Bake for 18 to 20 minutes or until lightly golden brown. Remove the crust from the oven and keep the oven on.

Step 3: Prepare the Rhubarb Curd

In a small heavy saucepan over medium heat, whisk together the egg yolks, sugar, lemon juice, lemon zest and 1/2 cup of the rhubarb sauce until smooth.

Add the butter cubes and cook while whisking constantly until the butter melts and the curd thickens slightly, about 6 to 8 minutes. If desired, stir in a drop or two of pink food coloring for a brighter appearance.

Pour the warm curd into the baked tart crust and spread evenly.

Step 4: Bake the Tart

Return the tart to the oven and bake for an additional 12 to 15 minutes, or until the center is almost set.

Remove from the oven and cool completely on a wire rack. Refrigerate the tart for at least 1 hour before serving.

Dust lightly with confectioners’ sugar just before serving if desired.

Variations

Replace pecans with walnuts or almonds for a different nutty flavor.
Add a few fresh strawberries to the rhubarb sauce for a sweeter filling.
Use orange zest instead of lemon zest for a citrus variation.
Top the tart with whipped cream for extra richness.
Add a thin layer of strawberry jam beneath the curd filling for added sweetness.
Make mini tartlets instead of one large tart for individual servings.

Storage/Reheating

Store the rhubarb tart covered in the refrigerator for up to 3 days. Because the filling is custard-based, refrigeration is important for freshness and texture.

To serve after chilling, let the tart sit at room temperature for about 10 minutes for the best flavor.

This tart is not ideal for freezing because the curd texture may change after thawing.

Reheating is generally unnecessary, as this dessert is best served chilled or slightly cool.
