For best results, ensure your milk or aquafaba is very cold. You can add a splash of vanilla extract, a pinch of cinnamon, or a drizzle of syrup (like caramel or chocolate) with your sweetener for flavored cold foam. Any fat content of milk can be used, but whole milk or 2% often yield the creamiest results. Aquafaba works best when chilled.
