Whisk together half-and-half, milk, apple cider, eggs, sugar, 1/4 tsp. ground cinnamon, salt, and nutmeg in a heavy saucepan. Cook over medium-low heat, whisking constantly, 15 to 20 minutes or until mixture thickens and coats a spoon. Remove from heat; stir in bourbon, if desired. Top each serving with sweetened whipped cream. Garnish, if desired.
I really love this recipe. Very addicting. I first used one like it in the SL Recipes 1984. This one is richer since it uses 1/2 & 1/2.
