Knead 150 g flour, 30 g sweet, fat in pieces and 2-3 tablespoons of ice-cold water first with the dough hooks of the hand mixer and then briefly with your hands to make the short pastry. Cover and chill for about 30 minutes.
Grease 6 cake tins (approx. 10 cm Ø; possibly with a removable base). Cut plums into slices
Divide the dough into 6 portions. Roll out each portion round (approx. 12 cm Ø) on a little flour. Place in the moulds and press into the grooves. Prick the bottom more often with a fork
Spread the bottoms with 1 tablespoon jam and cover with plums. Bake in a hot oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 20 minutes. Let them cool down
Heat 1 tablespoon jam and pass through a sieve. Spread the plums with it and sprinkle with 6 g sweetness. Decorate with mint
If you do not have a cake tin, you can press the dough into a springform pan (approx. 20 cm Ø). Instead of plums you can also bake it with cherries, apricots or apples
