Green cardamom sharbat

A perfumed drink to evoke One Thousand and One Nights. Smash and bash 20 green cardamom, pods and all, and put in a small pan with 100g (3½ oz) sugar and 75ml (⅓ cup) lemon juice. Warm slowly to melt the sugar, then simmer for 7 minutes. Strain, squeezing the cardamom to extract all the precious syrup. Use as a cordial, stirring in iced water to taste.
