How to make
The water is boiled in a coffee pot. Add the coffee - and as soon as it boils, remove it from the heat. Then return to the heat and boil again.
This is done a total of three times.
The yolk together with the sugar is beaten well with a wire - until a foam is formed.
It is added to the hot coffee very slowly and with constant stirring.
The coffee drink with egg yolk is served hot or cold.
