In a cocktail shaker combine mint leaves, lemon juice, vodka and raspberry syrup. Use a stirrer to muddle the mint leaves in the mixture.
Add in a handful of ice and put the lid on the cocktail shaker. Stir the mixture vigorously for around 10 seconds with a stirrer.
Tip the ice out of the martini glass. Strain the drink into the chilled martini glass.
Garnish the glass with fresh raspberries speared on a toothpick and a spring of fresh mint.
Notes
Raspberry Syrup:To make the raspberry syrup: combine 1½ cups raspberries, 1 cup sugar, 1 cup water, and 1½ tsp lemon juice in a saucepan. Simmer 10 minutes, strain well through a fine sieve to remove seeds, and cool completely. Full recipe at raspberry simple syrup.
Double strain through a fine mesh sieve to catch raspberry seeds and mint pieces for a clean drink.
Swap the vodka for gin for a different but equally good version.
Make the raspberry syrup ahead so it's completely cool before using.
