Real Irish Coffee

I found this recipe while surfing the internet. It's from A Little Irish Cookbook.

• Ready In: 10 mins
• Serves: 1

Ingredients

• 1⁄4 cup  hot strong black coffee
• 1 -2  teaspoon sugar
• 1 1⁄2 ounces  Irish whiskey
• 1 -2  tablespoon  double cream

Directions

1. Fill a stemmed whiskey glass with hot water then throw out, refilling it with boiling water. Throw this out, fill the glass somewhat more than half full with coffee and add sugar to taste.
2. Stir to dissolve, then add the whiskey. Pour the cream over the back of a spoon to float on top. Drink the hot liquid through the cool cream.
3. If double cream is not available use lightly-whipped single(whipping)cream.
