01 - Pulse flour, powdered sugar, and salt in a food processor. Add cold cubed butter and pulse until mixture resembles coarse crumbs. Add egg yolk and 1 tablespoon cold water, pulsing until dough begins to come together. Add additional water only if necessary for dough to form.
02 - Gather dough into a ball, flatten into a disk, wrap tightly, and refrigerate for 30 minutes. Preheat oven to 350°F. On a lightly floured surface, roll out dough and press into six 4-inch tart pans. Prick bottoms with fork.
03 - Line each tart shell with parchment paper and fill with pie weights. Bake for 12 minutes. Remove weights and parchment, then continue baking 8–10 minutes until golden brown. Cool completely in pans.
04 - Combine whole milk, heavy cream, and honey in a saucepan. Heat over medium heat until just simmering, stirring occasionally to dissolve honey.
05 - Whisk egg yolks, cornstarch, vanilla extract, and salt in a medium bowl. Gradually whisk hot milk mixture into yolks. Return mixture to saucepan and cook over medium heat, stirring constantly, until thickened about 3–4 minutes. Transfer to bowl, cover with plastic wrap directly on surface, cool to room temperature.
06 - Whisk eggs, egg yolks, sugar, lemon juice, and lemon zest in a saucepan. Cook over medium-low heat, stirring constantly, until thickened 5–7 minutes. Do not let mixture boil. Remove from heat and whisk in cubed butter until smooth. Cover with plastic wrap directly on surface and refrigerate until set.
07 - Spoon chilled honey custard into cooled tart shells, spreading evenly. Top with layer of lemon curd. Arrange fresh strawberry slices decoratively on top. Garnish with mint leaves if desired. Serve chilled.
