Irish Coffee - cooking recipe

Ingredients

1 1/2 ounces Irish whiskey
4 ounces strong black coffee
1 tablespoon brown sugar
3 -4 tablespoons heavy cream
boiling water
Optional
nutmeg or cinnamon

Preparation

Boil water and fill the glass mug to warm through. Dump out water.
Pour whiskey in glass, add coffee, sugar. Stir to combine.
