how to make?
1. Fill a stainless steel pitcher (pitcher) with cold milk.
2. Open the steamer for a few seconds before putting it in the jug to prevent water from entering the milk.
3. Insert the steamer about 5 mm into the milk diagonally when it is close to the side of the jug.
4. When the milk doubles in volume, insert the steamer deep into the jug.
5. Stop frothing, lightly tap the bottom of the jug on a firm surface and immediately after that pour in the espresso and drink.
