Ingredients for 22 cm baking pan:
7 eggs the closer to room temperature the better
180 g sugar
180 g flour
30 g potato starch
1/2 vanilla bean
Preheat oven to 160°
1. Sift the flour with potato starch and the vanilla's seeds. Mix well. In a separate bowl put the eggs with sugar and whisk them for about 10 minutes until you earn a very frothy cream, then add the flours and mix gently with a spatula, continue until all of the flour mixture is incorporated.
2. Spoon the cake mixture into the prepared pan and gently beat it on the table to remove air bubbles.
3. Bake for about 35 minutes or until nicely brown and a toothpick inserted into the centre of the cake comes out dry. You can fill it with ganache, fruits, whipped cream, jam whatever you prefer.
