Hot Whiskey Punch

Peel and slice the lemons; place the peel into a large non-reactive saucepan. Add sugar, cinnamon sticks, cloves and 3 cups of water. Set over a medium-high heat and stir frequently to dissolve the sugar. Allow the water to reach the boil, then turn heat down to minimum. Simmer for 10 minutes. Strain the mixture and return to the pan. Add the whiskey and heat but do not boil. Serve in Irish coffee glasses with a slice of peeled lemon in each. Makes 8 (6-ounce) Irish coffee glasses.
