This recipe was taken from Sundays at Moosewood Restaurant cookbook.

Ingredients:

2 oz. Unsweetened chocolate
2 cups milk
1 cup heavy cream
6 Tblsp sugar
1/2 tsp cinnamon
1 egg
1 tsp vanilla extract

Melt the chocolate in the top of a double boiler. In a separate pot, heat the milk and cream on low heat until hot, but not boiling. When the milk is hot, slowly add a little bit of it to the chocolate until you have a thin paste. Then stir in the rest of the milk and cream, the sugar and the cinnamon.

Beat the egg and vannilla in a bowl with a rotary beater. Add a very little of the hot chocolate to the egg (be careful so that the egg is not fried in the hot chocolate) and then stir the egg mixture into the hot chocolate. With a double boiler still on low heat, beat the chocolate with a rotary beater for 3 minutes. Serve immediately.
