How to Choose a Milk Jug
The ideal milk jug should be made out of stainless steel and should have a slight cone shape. During the whipping of the milk, it’s purpose is to capture and to hold back a good part of the heat produced by the steam and to facilitate the absorption of air. It must have a lip which is essential to perform cappuccinos and create latte art. We will need milk jugs of different capacities: 1 litre capacity milk jug, 3/4 of a litre and 1/2 of a litre. These measurements refer to their full volume. We will use a type of milk jug according to the number of cappuccinos required, please keep in mind that in order to perform the job correctly, the milk jugs need to be filled to half of their capacity. In the 1 litre milk jug we will pour about ½ a litre of milk, in the 3/4 of a litre one we will pour half of this capacity, in the ½ of a litre one we will pour 0.250 of a litre. Using classical cups that generally have a capacity of 180 cc. ,that means 18 cl., we will have 4 cappuccinos with the 1 litre milk jug, 3 cappuccinos with the ¾ of litre one and 2 cappuccinos with the ½ of a litre one. The milk that remains for a long time in the milk jug doesn’t have to be re-used. It would loose the quality of it’s whipping and above all the taste of the cappuccino.
