Unwaxed lemons - 4, washed
Golden caster sugar - 175 g
Water - 1 litre
Ice cubes to serve
1) Cut each lemon into 8 pieces and remove the pips. Place in a blender (I used a smoothie maker) with half the sugar and water.
2) Blend for a couple of minutes and then strain into a jug.
3) Tip the pulp back into the blender with the rest of the water and sugar and repeat. Discard the pulp and serve with ice. Serves 6-8.
