Buttered Rum: Create the batter by mixing a pound of brown sugar, a half-pound of butter, and a teaspoon each of cinnamon, cloves, and nutmeg. Add a little rum to give it a mousse-like consistency. To conjure a mug of hot buttered rum, start with a generous gob of batter, adding an equally generous dollop of rum and enough boiling water to reach the top. Drink.
