These are one of my favourite cocktails. I had them for the first time the summer before last at the Rooftop Film Club and I finally managed to get round to making them at Christmas, after craving them desperately.

Muddle some mint leaves in the bottom of a glass with a good squeeze of fresh lime, add ice and a generous measure of rum. Pour in pineapple juice, leaving an inch of space in the glass. Top up with ginger beer, and a dash of Angostura bitters.

Give it a stir, have a drink, shut your eyes and pretend you’re lying on a white sandy beach. Or sitting on top of a carpark in Ealing.
