A bright and creamy Ruby Red grapefruit curd tart baked up in a classic pâte sucrée crust and topped with maple swirled crème fraîche. 

This tart features a sweet pâte sucrée crust that bakes up crumbly and cookie-like. Because of the sugar, the dough can be a bit sticky, but keeping dough cold and rolling it between layers of floured parchment makes things easy. When making dough, be sure both the butter and egg yolks are at room temperature. Note that the dough needs to chill at least 4 hours before it can be rolled out.

Ingredients
Pâte Sucrée
  • 8 tablespoons unsalted butter, room temperature
  • 1/3 cup sugar
  • 1 egg yolk
  • 1/4 teaspoon sea salt
  • 1/4 teaspoon vanilla extract
  • 1 1/4 cups unbleached all-purpose flour
Curd
  • 2 Ruby Red grapefruits, preferably organic
  • 4 egg yolks
  • 3 eggs
  • 1/2 cup sugar
  • 3 tablespoons whole milk
  • 9 tablespoons unsalted butter, cut into cubes
Toppings
  • 1/2 cup crème fraîche
  • 1 tablespoon maple syrup
  • Thinly sliced citrus for garnish (I used grapefruit, Cara Cara oranges, and Kumquats)
Instructions
Pâte Sucrée
  1. In a large bowl or a stand mixer fitted with the paddle attachment, beat butter and sugar until pale and fluffy, about 4 minutes. Add yolk, sea salt, and vanilla and mix on low until well combined. Add flour and mix just until combined. Use a silicone spatula to fold in any dry bits. Be careful not to overwork dough.
  2. Gather dough into a flat round or oval (depending on the size of your tart pan), wrap tightly in plastic wrap, and refrigerate overnight, or at least 4 hours.
  3. When ready to bake, take dough out of fridge. It may need about 10 minutes to soften enough to roll. Set out either a 9-inch or rectangular 4 x 13-inch tart pan with a removable bottom. Line bottom with parchment and butter pan all over.
  4. Set out 2 sheets of parchment. Lightly flour bottom sheet, set dough in the center and scatter with flour, then cover with second sheet of parchment. Roll dough into either a 12-inch round or 7 x 16-inch rectangle. As you roll, peel up parchment and sprinkle dough with more flour to prevent sticking. When dough is the desired size, set on a rimmed baking sheet and chill 5 minutes.
  5. Press dough into prepared tart pan. Trim dough to a 1-inch overhang and then fold over along the sides. Save and chill any scraps to patch holes. Use the tines of a fork to poke holes all over. Set pan in fridge and chill at least 20 minutes.
  6. Preheat oven to 350 degrees F. When tart is chilled, set on a rimmed baking sheet and bake until it just blushes golden, about 15 minutes. As long as it's properly chilled, tart shell doesn't need weights.
  7. Set tart shell aside to cool while you make grapefruit curd.
Tart
  1. Carefully peel zest from one of the grapefruits and cut into very 2-inch long slivers.
  2. Juice grapefruits and measure 3/4 cup juice. Reserve any remaining grapefruit for garnish.
  3. Set a large, non-reactive sauce pan over medium heat. Whisk to combine yolks and eggs, sugar, milk, and sea salt. Stir in juice, 3 tablespoons zest, and butter. Cook, stirring constantly, until mixture is pale, frothy, and thick enough to coat the back of a wooden spoon, 5 - 7 minutes. Take care that mixture doesn't boil, as this will curdle the eggs.
  4. Set mixture aside to cool for about 30 minutes.
  5. When ready to bake tart, fill cool crust 2/3 full with curd, set on rimmed baking sheet, and bake just until curd is puffed up and set, 15 - 20 minutes. Check after 15 minutes, and then check in 2 minute increments until filling is just set.
  6. Set on a wire baking rack to cool.
  7. In a small bowl, whisk with a fork to combine crème fraîche and maple syrup. Serve tart with generous dollops of crème fraîche and sliced fruit. The crust is best day of, but tart will keep for 2 days covered in the fridge.
