Halloween Libations: The Pumpkin Martini

I've been on the hunt for the perfect Pumpkin Martini for years. I think I've found it - it doesn't need the flavored liqueurs (e.g.Hiram Walker's neon orange Pumpkin Liqueur...), nor does it rely on flavored vodka (too sweet). Just the right mix of fresh ingredients and kick!

2 T pumpkin puree (yes, real puree. Use from a can if you don't want to mess with a real pumpkin)
1/3 cup milk or cream
1 pinch pumpkin pie spice
Mix these together in a shaker with some ice, then add:
1.5 oz vodka
.5 oz creme de cacao (white or dark)
Add a little more ice, shake until foamy, strain into a martini glass and garnish with a shake of nutmeg or cinnamon!
Halloween Gold!
