This makes two drinks.
Add a handful (3 or 4) frozen or fresh strawberries to your mixer. Fill it up the rest of the way with ice. Add four ounces of vanilla vodka. Put the lid on and shake like crazy (a good minute or so).
Drop a frozen (or fresh) strawberry at the bottom of your martini glass. Strain equal portions of the vodka into each glass. Voila!
Variations: we like to add two parts vanilla vodka and two parts other flavored vodka. Orange works well, and strawberry vodka makes for a sweeter drink.
