Kogel mogel

Kogel mogel is an egg-based homemade dessert once popular in parts of Europe. It is made from egg yolks, sugar, and flavourings such as honey, vanilla, cocoa or rum, similar to eggnog or zabaione. In its classic form it is served slightly chilled or at room temperature. Served warm or hot, it is considered a home remedy for sore throats. Variations include milk, honey and soda. Kogel mogel became known by this name by the 17th-century Jewish communities of Central Europe. It may have its roots in the Jewish code of law called the Shulchan Arukh where one is allowed to consume sweet syrup and/or raw egg on Shabbat to make one's voice more pleasant. Vasmer's dictionary mentions different hypotheses on the origin of the name such as English hug-mug, hugger-mugger, or German Kuddelmuddel.
