The Tip: Shake it until it's snowy.

What you'll need for two delicious Six Thirty Dirty Martinis

• Lots of ice
• 180ml of your favourite vodka
• 1 cap of Martini & Rossi extra dry vermouth
• 1 tablespoon of olive brine
• High quality olives

Fill your shaker with ice and add the vodka, vermouth and olive brine. Close it tightly and shake it for ages until it’s all snowy on the outside. Place your desired number olives into the bottom of a martini glass, strain over half of your icy cold mixture, and repeat with the remaining olives and mixture in another glass. Give one to a lucky friend.
