A very typical Venetian cake, very old but still very nice!
Ingredients:
200 gr of potato flour
200 gr of butter
200 gr of caster sugar
2 eggs (separated, whip the eggs white very firm)
25 gr baking powder
salt
icing sugar to decorate
Line and flour a baking tin 22cm.
Beat the butter with the sugar for a while until pale and fluffy. Add the egg yolks, then the flour and the baking powder. and a pinch of salt. Add the egg whites and mix well. Place the mixture in the tin and bake in the oven at 180 degrees (gas mark 4) for about 40 minutes. DO NOT OPEN THE OVEN DOOR for the first 30 minutes (the cake will go flat – believe me, it happens – we did that!!). Cook until nice golden and firm.
Take the cake out of the oven, let it cool, place it on a serving dish and dust with icing sugar.
