Grease a springform pan (26 cm Ø), fill in the dough and smooth it down. Bake the cake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 45-50 minutes. Remove, remove from the edge of the springform pan and allow to cool. Wash, clean and halve the strawberries. Soak 2 sheets of gelatine in cold water. Bring 440 ml milk to the boil.

Remove the pudding from the heat, allow to cool slightly and stir in the squeezed gelatine. Cover the surface with foil and let it cool down for about 30 minutes. Squeeze lemons. Mix lemon juice and icing sugar. If necessary, straighten the top of the cake slightly, then divide it horizontally (upper part approx. 1/3). Hollow out half of the base, leaving a rim about 1 cm wide and place in a cake ring. Brush the lemon-sugar-mix onto the cut surface of the lid and onto the edge of the cake base.
