Whip egg whites stiff, while still whipping among vinegar and sugar in little by little until the mixture is thick like meringue.
When the dough is baked finished, take it out after which the selected fruit or compote is distributed over the cake while still hot,
then spread the meringue beyond the fruit crop or the compote,
For example, you can iron the flat or use a spray bag to make tops all over the cake,
then baked the cake for 10 minutes at the same temperature.
The meringue must be golden.
