Step 1

Start by making the sugar syrup. Put the caster sugar in a small pan over a medium heat and pour in 50ml water. Stir, and bring to the boil.

Step 2

Turn off the heat and allow the mixture to cool. Put 2 martini glasses in the fridge to chill.

Step 3

Once the sugar syrup is cold, pour 1 tbsp into a cocktail shaker along with a handful of ice, the vodka, espresso and coffee liqueur. Shake until the outside of the cocktail shaker feels icy cold.

Step 4

Strain into the chilled glasses. Garnish each one with coffee beans if you like.
