Knead the flour, baking powder, almonds, butter, eggs, icing sugar, cinnamon, cloves and lemon zest first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Cover and chill for about 1 hour. Roll out 2/3 of the dough on a greased baking tray (32 x 39 cm). Stir the jelly until smooth and spread on top. Roll out the remaining dough thinly on a floured work surface. Cut into strips of approx. 1.5 cm width using a dough wheel.
Place strips diagonally as a grid over the jelly at a distance of approx. 1 cm. Whisk 1 egg yolk and brush the grid with it. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 35 minutes. Let it cool down and dust with icing sugar. Whipped cream tastes good with it
