To make the jam poured cake, start by whipping the eggs with the sugar until the mixture is thick and fluffy. Add flour, baking powder and starch WELL SET, alternating them with the milk. This will make it easier to obtain a very smooth and homogeneous dough. Transfer half of the mixture into a well buttered and floured 24 cm diameter mould. Level it out well and bake in a preheated, static oven at 180° for 20 minutes. Remove from the oven, spread the jam over the entire surface and cover with the remaining mixture, gently levelling off. Continue cooking, at the same temperature, for another 30-35 minutes, testing at the end with a toothpick. Take the cake out of the oven and let it cool completely before sprinkling it with icing sugar.
