Knead the flour, baking powder, almonds, butter, sugar, salt, egg and 1 tablespoon of cold water into a smooth short pastry. Wrap in cling film and chill for 1 hour. Drain the cherries, collect the juice and measure 400 ml. Mix the juice, 4 tablespoons of liqueur and pudding powder and bring to the boil. Add the cherries and cook for 1 minute, stirring gently. Leave to cool.
Grease a tart tin (26 cm Ø) and sprinkle with 2 tablespoons of breadcrumbs. Roll out the dough on a floured work surface. Cut out a circle (30 cm Ø) and place it in the tin. Press firmly and remove any excess dough. Prick the base several times with a fork. Sprinkle the rest with breadcrumbs and flaked almonds. Chill for about 15 minutes. In the meantime roll out the rest of the dough. Cut strips of 1/2 cm width with a dough roller. Add the cherries to the tart. Place the strips of dough as a grid on the cherries and press them on the edge. Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) on the lower rack for about 25 minutes.
