Smash up the graham crackers, cinnamon and sugar together. Get the rim of your glass wet and dip it into your cinnamon, sugar, cracker mix. PROTIP: use maple syrup on the glass and you’ll get extra flavor and sticking power.
Combine everything else into your cocktail shaker. Shake like a bandit. Pour and strain into your magnificently rimmed martini glass. Garnish with a little bit of grated nutmeg (fresh, naturally).
NOTE: If you're interested in making your own pumpkin pie spice try, 4 parts cinnamon, 2 parts ginger, 1 part nutmeg, 1 part allspice, 1/2 part cloves.
