Dirty martinis can be made from vodka or gin, and they are mixed with olive brine and vermouth and garnished with olives. The Food Network, Martha Stewart and Epicurious websites all offer simple recipes for dirty martinis.
Dirty martinis should be served cold and can be poured onto ice. To ensure a cold drink, store the vodka or gin in the freezer before use.
The Food Network website features a dirty martini recipe that utilizes gin instead of vodka. To make the dirty martini, mix 2-1/2 shots of gin with 1/2 shot of olive juice brine and 1/8 shot of extra-dry vermouth. All of the ingredients should be shaken in a cocktail shaker over ice and strained. Pour the martini in a martini glass onto ice.
The dirty martini recipe listed on Martha Stewart's website uses 2 ounces of vodka or gin, 4 to 5 teaspoons of olive brine and a splash of dry vermouth. Mix all of the ingredients onto ice in a cocktail shaker and pour into a martini glass over ice. Garnish with green olives.
The Epicurious website lists a recipe for ten dirty martinis. The recipe calls for chilled martini glasses, and 1/4 cup of vodka is poured into each of the ten glasses. Add in 1 tablespoon of olive juice from the jar into each glass and garnish with an olive.
