Waiting: 30 minutes 
Oven: 30 minutes

• In the food processor or with the mixer, knead a smooth dough consisting of the butter, 125 g of sugar, the flour, the flour, one egg, and a pinch of salt. Let the dough rest in the fridge wrapped in cling film for 30 minutes. 
• Preheat the oven to 180ºC. Place a sheet of baking paper on the bottom of the spring form pan and close the form. Roll out two thirds of the dough into a layer 3 mm thick. Place into the spring form pan leaving a raised edge of 3 cm. Sprinkle the sweet potato cubes on the dough base. Divide the jam over it, and smooth it out. 
• Beat the second egg. 
• Roll out the rest of the dough into layer 3 mm thick. Cut the dough into wide strips. Make a lattice on top of the pie. Thinly brush the lattice with beaten egg, and sprinkle with the rest of the sugar. 
• Bake the crostata in the preheated oven for about 30 minutes until golden brown. Let the crostata cool in the spring form pan. 
• Dust the cake with icing sugar just before serving.
