Rub the soft butter with the sugar and vanilla sugar. Add the egg, salt powder, vanilla essence and sour cream. Add baking soda and baking powder quenched with a tablespoon of vinegar. Everything is homogenized. Gradually add the flour and knead until a non-sticky crust is obtained. Leave to cool for at least 15 minutes.
Peeled apples and seeds are given through the large grater of the food processor, after which they are hardened together with the sugar and vanilla sugar until all the juice they leave decreases.
Divide the dough in half, spread the first sheet on the work table (greased with oil and floured) and then transfer to the plate (greased with oil) from Panini Maker Breville. Prick the sheet from place to place with a fork, then sprinkle a tablespoon of semolina. Spread the apples over the sheet and sprinkle the cinnamon over them.
On the work table (greased with oil and floured), spread the second sheet with the help of a twister, then roll it on it and place it over the apples. Prick this sheet, from place to place, with a fork. Press the dough on the edges to stick, then turn on the appliance and leave the pie until it browns nicely.
