This martini, with a typically Ottolenghi Middle-Eastern twist, is one of the most popular welcome drinks on Nopi’s cocktail list.

Sumac martini

Serves 1

For the sumac vodka
100ml vodka
10g sumac, plus extra to garnish

For the drink
25ml sumac-infused vodka (see above and method)
15ml Velvet Falernum liqueur
20ml pomegranate juice
20ml fresh lime juice

First make the infusion. Pour the vodka into a small clean jar, add the sumac, then seal and leave to infuse for 10 hours. Strain through a cloth or coffee filter into a second clean jar.

To make the drink, put everything in a shaker filled with ice, shake hard for five or six seconds, then double strain into a martini glass. Sprinkle a small pinch of sumac over the top and serve.
