Instructions

Cream softened butter and powdered sugar until smooth. Add egg, almond flour, salt, and all-purpose flour. Mix until just combined, then roll dough and refrigerate for 1 hour.
Press dough into a tart pan, prick the base, and chill briefly. Bake at 160°C (325°F) for 20–30 minutes until golden. Cool completely.
Heat milk with vanilla until just boiling. In a bowl, whisk egg yolks, sugar, and cornstarch. Slowly add hot milk while whisking.
Return mixture to low heat and stir continuously until thickened. Once boiling, cook for 30 seconds, then cool with plastic wrap covering the surface.
Cook rhubarb with sugar, water, lemon juice, cinnamon, and star anise for 5–10 minutes until tender. Remove spices and mash into a compote. Cool.
Spread custard evenly over the cooled tart shell.
Top with rhubarb compote and smooth the surface.
Refrigerate the tart for at least 30 minutes before slicing and serving.

Notes

Do not overwork the dough to keep the crust tender and flaky.
Stir custard constantly to avoid lumps or burning.
Cook rhubarb until just tender to maintain texture.
Allow the tart to cool completely before slicing for clean layers.
Store in the refrigerator for up to 3 days.
