Mario Batali attributes* this killer drink to Clinton Kelly, his co-host on some TV show. It's the Autumn Margarita. I'd like to call it the Autumn Bottom Margarita after a fabulous, warm, generous woman I work with named Autumn (whose nickname is Bottom).
6 oz fresh apple cider
4 oz white tequila
juice of one lime
cinnamon sugar to rim the glasses (hint: use more sugar than cinnamon)
sliced apple for garnish
Fill a shaker with ice. Add cider, tequila and lime juice. Shake like hell. Pour into rocks glasses rimmed with cinamon sugar.
It's a good reason to keep tequila on hand 365 days/year.
