Preparation

Rinse a mug or heatproof cup with boiling water to warm it. Add 1 teaspoon Demerara sugar and a swatch of thin-cut lemon peel. Add 1 oz boiling water and stir to dissolve the sugar. Add 2 oz brawny single malt Scotch (Macallan or, if insane or very cold, Ardbeg). Finish by adding 1 oz more of boiling water to bring the heat back up.
