Nutmeg date shake

For a Californian road trip in a glass, freeze 200ml (generous ½ cup) milk in ice-cube trays. In a high-speed blender, whiz the milk ice with 2 pitted medjool dates, a grating of nutmeg and a suspicion of salt. Add a good glug more milk to help the blades turn and make a thick, toffeed milkshake. Drink at once and dream of sunshine.
