Ingredients
For the biscuit and lemon cream cake recipe, cut the lemons in half; make some thin washers to hold as the final seal, then squeeze them, obtaining 120-130 g of juice. Mix the eggs with the granulated sugar and the flour; add the lemon juice, little by little. Thicken the mixture over the heat, stirring it, for 10-12 minutes.
Cover a rectangular mold (25 × 10 cm, h 4 cm) with baking paper; form a layer with 50 g of biscuits; crumble those that remain and use them to fill the cracks between a biscuit and another.
Pour the lemon cream over the biscuits and bake at 170 degrees for about 15 minutes. Turn out the cake with the baking paper of the covering and let it cool in the fridge for an hour. Garnish it before serving with the lemon washers and a sprinkling of powdered sugar.
