Add all ingredients to a cocktail shaker

Step 3

Chuck in plenty of ice and shake vigorously and briefly

Step 4

Strain into tall glass

Step 5

Add your rolling-pin-crushed ice until just shy of the rim

Step 6

Slowly and gently pour your port over the top, so it ‘floats’ on the drink

Step 7

Add more crushed ice to create a dome of ice

Step 8

Garnish with mint sprigs and and skewered lychees and blackberries – if you’re going for a Halloween theme, stuff the blackberries into the lychees to create some spooky eyeballs
