Making a cappuccino, a latte macchiato, or a flat white at home is easy with a milk frother. With an electric milk frother, you can make wonderfully warm milk foam, warm milk, or even cold milk foam. The frothing works as follows: fill the jug with fresh, cold milk of your choice and turn on the milk frother at the touch of a button. Pour the milk in your coffee and your homemade milk specialty.
