The term “dirty” when used in conjunction with a martini, is simply the addition of olive brine from a jar of olives. It can be added to taste but is generally ¼ – ½ ounce per drink. If you want a “Filthy” Martini, simply add more brine 😉
The olive brine offers a taste of “umami” which would add a savory quality of saltiness and acidity with a hint of sweetness to your drink.
2 ½ ounces of high-quality gin (or vodka if preferred)
½ ounce of dry Vermouth
¼-1/2 ounce of olive juice
Garnish: 1-3 olives.
