Ingredients

200g ginger
thickly sliced
2 large lemons
peeled and juiced
75g golden caster sugar
100g light brown muscovado sugar
ice
1 litre soda
or sparkling water
mint
sprigs, to serve

Method
step 1
Put the ginger in a saucepan set over a low heat with the lemon peel, sugars and 500ml water and stir until the sugars have dissolved. Increase the heat to medium, then simmer for 15-20 mins, or until reduced and syrupy. Remove from the heat and leave to cool completely.

step 2
Strain the syrup into a jug through a sieve lined with muslin. At this stage, you can transfer the syrup to a small sterilised bottle or jar and keep in the fridge for up to two weeks.

step 3
Pour the ginger syrup into a large serving jug. Tip in the lemon juice, fill with ice and top up with the soda water. Serve garnished with a few mint sprigs.
