1/2 c. sugar
1/3 c. unsweetened cocoa powder
2 tbsp. flour
1 tsp. ground cinnamon
1/2 tsp. salt
1 1/2 c. cold water
6 c. milk
1 tbsp. vanilla

Combine sugar, cocoa, flour, cinnamon, and salt in a large saucepan. Stir in cold water and bring to a boil, stirring constantly. Reduce heat and simmer, stirring often. Slowly stir in milk; add vanilla. With a rotary beater or mixer, beat the mixture until it is frothy. Serve in mugs or cups, garnishing each with cinnamon stick or a dollop of whipped cream. This is an unusual and delicious holiday drink. Makes 10 servings.
