They are called Merengue after the town Meiringen in Switzerland, where an Italian baker invented them.
5 Egg whites
1/2 tsp Cream of Tartar
240 g Icing Sugar
You can add one of these for taste:
1/2 tsp Vanilla Extract
or 1/2 tsp Coffee Extract
or 1/2 tsp Strawberry Extract
or 1/2 tsp Orange Extract
or 1/2 tsp Cocoa Powder
or 1/2 tsp Almond Extract
Beat the egg-whites in a glass- or metal bowl. When the egg-whites are almost stiff add the cream of tartar and go on beating. The slowly add the sugar, go on beating. I use the Kenwood machine or else my arm would fall off.
You know the merengue is ready when you can rub some between your fingers and you can feel no sugar.
