Method

• 1.
  Fill the martini glass with ice and leave to chill. Half-fill a cocktail shaker with ice.
• 2.
  Pour the dry vermouth over the ice and use a long handled spoon to stir around the inside edge of the shaker 2-3 times. Strain, discarding any excess vermouth (this leaves a coating of vermouth on the ice).
• 3.
  Pour the gin over the vermouth-coated ice and use the long handle spoon to stir the inside edge (this is to avoid bruising or diluting the gin) of the shaker for a further 2-3 times.
• 4.
  Remove and discard ice from the glass and pour martini into the chilled glass. To garnish, thread the olive onto a short cocktail stick, and place in the glass. Alternatively, garnish with a twist of lemon.
