To make a batch of 4 you need
5oz of Tanqueray gin
2 heaped teaspoons of Genmai Cha
Japanese green tea
3oz of fresh lime juice
2oz of sugar syrup (Easy to make, its equal amounts of sugar to water heated until the sugar is dissolved and left to cool. I make up enough to fill a bottle and keep it in the fridge)
4 lime wheels as a garnish
Ice
Method
Put the tea into the gin and leave to infuse overnight
Leave glasses in the freezer to chill
Drain tea-infused gin. (I'm sure you
can buy some fancy gadget to do this, but I use a clean pop sock)
Squeeze limes
Fill a cocktail mixer with ice, add gin, lime juice and sugar syrup stir until thoroughly chilled
Pour into chilled glasses
Add lime wedge garnish
