Recipe: Bourbon Milk Punch

This is (basically) the Commander's Palace recipe.  Pete Fountain can't be wrong.

1 1/2 c. 2% milk
1/2 c. heavy cream
12 oz. bourbon (Maker's Mark is the rail in our house)
1 egg white (NOT optional, even if the recipe says it is)
1/2 c. simple syrup
1 Tbsp. vanilla extract (the real stuff, not the fake stuff)

Combine the milk, cream, bourbon, egg white, sugar, water and vanilla in a pitcher. Mix using an immersion blender. Serve over rocks in old fashioned glasses with a grind of nutmeg on the top.
