Cover and chill for about 1 hour. Roll out 2/3 of the dough on the greased fat pan of the oven (32 x 39 cm). Spread jelly on top. Roll out the remaining dough thinly on a floured work surface.
Use a dough wheel to cut into strips of approx. 1.5 cm. Place strips diagonally as a grid over the jelly at intervals of approx. 1 cm. Bake in the preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for 25-35 minutes. Allow to cool and dust with icing sugar
