Place the puff pastry slices next to each other and defrost. Wash, halve, stone and cut the peaches into slices. (Drain canned peaches, cut into slices). Grease a rectangular tart tin with removable base (approx. 20 x 28 cm) at the bottom. Place puff pastry slices on top of each other and roll out into a rectangle (approx. 22 x 30 cm) on a floured work surface. Line the mould with the dough, press down at the edges. Sprinkle the base with almonds.
Spread the peach halves on the base. Bake in the preheated oven on the lowest level (electric oven: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 30 minutes. Heat up the jam and pass through a sieve. After approx. 15 minutes baking time, coat the tart with jam and sprinkle with sugar. Cover if necessary. Let it cool down
