Instructions

Base

Beat egg whites with sugar with a hand electric mixer until stiff white foam, gradually stir in hot water and oil by spoonfuls and then only with a spatula mix flour with baking powder and finally fold in beaten egg whites with a pinch of salt. Spread the batter on a large deep baking sheet (42x32cm, greased with butter and dusted with coarse flour only on the bottom) and bake for 20 minutes at 170 degrees.

Let it cool, spread with spicy jam (I used homemade blackcurrant), half of the cream, place ladyfingers soaked in coffee with rum, spread with the remaining cream, spread whipped cream on top and decorate with Granko.

Cream

Cook a thick pudding from milk, sugar, pudding powder, and instant coffee and stir in butter while still hot. Let it cool and then thoroughly whisk with an electric mixer, gradually whisk in sour cream and divide into two halves.

Soak ladyfingers in coffee with rum and place on the cream. Cover with the second layer of cream. Whipped cream for decoration (I used 3 sachets of instant whipped cream and 300ml of cold milk), Granko for sprinkling. Let it set in the fridge until firm.
