Mix pudding powder, 4 tablespoons of milk and sugar. Bring the remaining milk to the boil, stir in the pudding powder and bring to the boil again. Let cool while stirring. Defrost puff pastry slices side by side on the work surface. Place the slices in 6 greased tartlet cups (approx. 10 cm Ø) and press them down slightly. Leave the pastry corners to lap over the tartlets. Prick the pastry several times with a fork.
Line with parchment paper, place dried peas on top and bake in a preheated oven (electric range: 200 °C/ gas: level 3) for approx. 12 minutes, blind-baked. Remove the legumes and parchment paper, let the puff pastry bases cool down. In the meantime lightly roast the flaked almonds in a pan without fat. Spread the pudding on the bases. Spread the berries on top. Sprinkle the tartlets with roasted almonds
