A simple idea. A sour drink made with corn. Bourbon as the spirit, lemon for the sour and a homemade corn syrup for the sweetener. I took three corn husks (having previously cut the corn kernels off to make Yotam Ottolenghi's amazing Sweetcorn Polenta), covered them with water and boiled for 20 minutes. I strained the liquor, reboiled it reducing it to half the volume and then added about 4 tablespoons of golden caster sugar and boiled it for a further 5 minutes. I was left with about 100ml of lightly sweet corn syrup. Given it isn't too heavily sweet I adjusted back the volume of lemon juice to find the right balance. Sometimes simple can be delicious.
