I just finished a variation of the aforementioned Vieux Carre that was very nice, and would make a great Thanksgiving cocktail:
3/4 oz. Laird's bonded apple brandy
3/4 oz. Old Forester BIB (1980s version: orange, cherry, flowers, and cinnamon)
3/4 oz. Cinzano sweet vermouth
1 tsp. Cherry Marnier (not always available: any good cherry flavored brandy liqueur will work)
2 dashes Peychaud's
2 dashes homemade bitters (similar to Fee Bros. Aromatic - lots of cardamom and cinnamon)
Stir with ice and strain. Flame an orange peel over the glass.
I really dig the interaction of fruitiness here: apple, orange and cherry (from the vermouth, the whiskey, and the Marnier) are great together. Then throw in the pie spice from the bitters and whiskey. Superb.
