Remove from the oven, place on a rack and allow to cool. In the meantime, wash and clean the strawberries and drain them well. Select the raspberries and blackberries. Wash and sort the blueberries and drain them well. Wash the lemons thoroughly and grate the peel finely. Halve the lemons and squeeze the juice. Soak gelatine in cold water. Mix yoghurt, 150 g sugar, lemon zest, lemon juice and 1 sachet of vanillin sugar. Squeeze the gelatine and melt it at low heat. Remove from the stove. Stir in 5-7 tablespoons of the yoghurt mixture. Then stir into the remaining yoghurt mass. Chill the yoghurt mass for approx. 20 minutes until the mass begins to gel (roads pull).
