answer:This is my recipe for Cosmos for a crowd. Cosmopolitans for a Crowd 18 -24 oz. fluid ounces lemon vodka 12 fluid ounces Cointreau 12 fluid ounce cranberry juice ¾ cup freshly squeezed lime juice ¾ c simple syrup Combine vodka, Cointreau, cranberry and lime juices. Stir well to combine and chill. Shake each drink with ice and strain into a chilled martini glass. Twist orange zest over each drink and serve. Recipe can be easily multiplied. I’ve made this recipe for a low carb crowd using water mixed with Splenda instead of simple syrup made with sugar. Make a splenda slurry using the amount of water = the simple syrup called for in the recipe and add splenda to taste (use less than you think you will need). It works well and either way—a large batch can be made in advance and chilled. Makes for easy entertaining. not my work. I stole it from this site.
