01 - In a food processor, pulse flour, powdered sugar, and salt. Add butter and pulse until mixture resembles coarse crumbs. Add egg yolk and 1 tbsp cold water, pulsing until dough begins to come together (add more water if needed). Gather dough, flatten into a disk, wrap, and chill 30 minutes.
02 - 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 12 minutes. Remove weights and parchment, bake 8–10 minutes more until golden. Cool completely.
03 - 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, stirring constantly, until thickened (about 3–4 minutes). Transfer to a bowl, cover with plastic wrap touching surface, cool to room temperature.
04 - Whisk eggs, yolks, sugar, lemon juice, and zest in a saucepan. Cook over medium-low heat, stirring, until thickened (5–7 minutes; do not boil). Remove from heat and whisk in butter until smooth. Pour into a bowl, cover with plastic wrap touching surface; chill until set.
05 - Spoon honey custard into cooled tart shells, smoothing tops. Add a layer of lemon curd over custard. Arrange strawberry slices on top. Garnish with mint leaves if desired. Serve chilled.
