We remove the oil in the freezer. We turn on the oven 180 degrees.
Mix sugar, flour, semolina, soda, cinnamon and vanillin.
Rub apples on a coarse grater. Grease a baking sheet with oil.
We divide the dry mixture into 4 parts, and divide the apples into 3 parts. I pour one part of the dry mixture onto a baking sheet. Top with a layer of apples.
The top layer is dry. On top of it, grate the butter and the apple pie is sent to the oven for 45 minutes until slightly ruddy.
Cool the apple pie and sprinkle with icing sugar.
