|Minimum 2 egg whites||3||/||/|
DO NOT use cold egg whites; eventually, set temperature to 40 °C. Also, notice that a few drops of lemon juice will help the preparation,and remove part of the strong flavor of eggs.
TIP: to get the highest possible volume, add the sugar only after the whites have quadrupled their volume. Of course, if you prefer instead denser meringues, you can add part of the sugar immediately.
