For the yeast dough, crumble the yeast into a small bowl. Mix with sugar until the yeast becomes liquid. Put flour, 1/2 tsp salt and 2 tbsp oil in a bowl. Add approx. 125 ml lukewarm water and yeast and immediately knead to a smooth dough with the dough hooks of the hand mixer. Cover and leave to rise in a warm place for approx. 45 minutes until the dough has doubled
Peel the pumpkin thinly and cut into very thin slices. Clean and wash spring onions and cut into rings. Stir sour cream until smooth, season with salt and pepper. Line a baking tray (approx. 32 x 38 cm) with baking paper
Knead the dough once more and quarter it. Roll out in portions on a floured work surface until oval. Place 2 pastry sheets on each baking tray. Spread doughs with sour cream. Spread vegetables on top. Bake in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: see manufacturer) for about 15 minutes. In the meantime, clean, wash and shake dry the rocket. Sprinkle the finished tarte flambée with rocket. Do the same with the rest of the dough. Serve ready tarte flambée immediately. Raw ham tastes good with it
Waiting time approx. 40 minutes
