Egg Mousse for Coffee or Tea

This egg mousse is traditionally served with coffee or tea at a Yom Kippur break-fast in Sephardic communities and I’ve found it in countries as diverse as the Dutch West Indies and Morocco. The idea behind it is that the eggs and sugar give you strength after fasting. Traditionally, the mousse is made with egg yolks, but whites will mousse nicely with considerably less fat.
