01 - Pulse flour, powdered sugar, and salt in a food processor. Add butter and pulse until mixture resembles coarse crumbs. Add egg yolk and 1 tbsp cold water, pulsing until dough begins to come together, adding more water if needed. Gather dough, flatten into a disk, wrap, and refrigerate for 30 minutes. Preheat oven to 350°F. Roll out dough and press into six 4-inch tart pans. Prick bases with a fork. Line with parchment and fill with pie weights. Bake for 12 minutes. Remove weights and parchment, bake 8-10 minutes more until golden. Cool completely.
02 - Heat milk, cream, and honey in a saucepan until just simmering. In a bowl, whisk egg yolks, cornstarch, vanilla, and salt. Gradually whisk hot milk mixture into yolks, then return to saucepan. Cook over medium heat, stirring constantly, until thickened for about 3-4 minutes. Transfer to a bowl, cover with plastic wrap touching the surface, and cool to room temperature.
03 - Whisk eggs, yolks, sugar, lemon juice, and zest in a saucepan. Cook over medium-low heat, stirring constantly until thickened for 5-7 minutes, being careful not to boil. Remove from heat and whisk in butter until smooth. Pour into a bowl, cover with plastic wrap touching the surface, and refrigerate until set.
04 - Spoon honey custard into cooled tart shells, smoothing the tops. Add a layer of lemon curd over the custard. Arrange strawberry slices on top. Garnish with mint leaves if desired. Serve chilled.
