Mirabelle plum tart
Lorraine grows most of the world's mirabelles, small golden plums with a blush of red that ripen for only a few weeks from mid-August, when Metz holds its Mirabelle festival and every pâtisserie in Nancy fills its window with this tart. The plums are halved and packed tightly into a crisp shortcrust, sometimes over a thin layer of almond or semolina to soak up the juice, and they bake into a jammy, honey-sweet layer. Families eat it warm or cold for Sunday dessert or at four-o'clock goûter. Out of season, use small yellow plums or halved apricots. Chef's tip: stand the halves upright and overlapping, cut side up; they shrink as they bake, and a tight layer stops the tart looking bare.
