Santa Claus Melon Tart

Heat oven to 350°. In a food processor, pulse flours and 1⁄2 teaspoon salt until combined. Add 12 Tbsp. butter and pulse until pea-size crumbles form. Pour in water and pulse until dough comes together. Shape dough into a disk and cover with plastic wrap; chill for 1 hour.

On a lightly floured surface, roll dough into a 12" circle; press into a greased 11" tart pan with a removable bottom set over a baking sheet. Using a fork, prick the dough all over; line with parchment paper and fill with pie weights; bake 15 minutes. Remove paper and weights; cook 15 minutes more. Cool completely.

In a blender, purée half of the melon until smooth, then strain through a fine mesh sieve, reserving 3⁄4 cup juice. Cut the remaining half of melon into thin slices; set aside. In a 4-qt. saucepan, whisk together the remaining salt, the reserved melon juice, the eggs, egg yolks, 1 cup sugar, and 1 teaspoon lemon zest. Cook, stirring, over medium heat, until the mixture thickens, about 8 minutes. Remove from heat; whisk in the remaining butter 1 tablespoon at a time until incorporated. Strain the curd through a sieve set over a large bowl. Pour into cooled tart crust. Freeze tart until set, about 1 hour.

In a 1-qt. saucepan, bring the remaining sugar and lemon zest, the mint, and 2 Tbsp. water, to a simmer over medium heat. Cook until sugar is dissolved, about 3 minutes. Strain through a fine mesh sieve and cool, discarding solids. Arrange sliced melon into a concentric circle on the tart and brush with syrup. Garnish with sliced almonds.
