A perfect cup of coffee, for some, must be topped with a bit of steamed milk. In U.S. coffee shops, baristas--who are thoroughly trained to make you a perfect cup of coffee--employ steaming machines to create the frothy milk. You can do it yourself at home without investing in expensive equipment. Steam any kind of milk ... whole, 2 per cent, skim or soy; the froth will be different for each, so you should experiment to find out which you like the best. Fresh milk froths the best, and milk with a higher fat content will taste sweeter.
Fill the jar with as much milk as you would like to add to your coffee or other hot drink.
Place the lid tightly on the jar, and shake it for approximately 30 seconds to create frothy bubbles.
Remove the lid from the jar, and immediately place the jar in the microwave. Heat the milk on high for about 30 seconds. The froth will rise to the top of the milk.
Place a large spoon inside the mouth of the jar to hold back the froth as you pour the milk into your drink. Then, pour the froth onto the top of your drink.
Don't fill the jar any more than halfway, so there's room for the froth.
