Don’t confuse this fall cocktail with a green apple martini.  Apple pie martinis are made with vodka, apple cider, whipped cream and cinnamon, served in a graham cracker–rimmed martini glass.  To make this tasty drink: Wet rim of martini glass with apple cider and dip rim in a plate of graham cracker crumbs.  Use one part vanilla-flavored vodka (or regular vodka) and two parts apple cider, shake with ice in a cocktail shaker and strain liquid into prepared glasses.  Top with whipped cream (canned works well) and sprinkle cinnamon on top.  Serve these with a warning that they may taste smooth, but they are potent.
