The better way is with a "milk frother" or a frappe, a small hand held, battery operated coffee mixer. They come really cheap and are very useful. If you are using a frother, then place it (still turned off) into the cup with the coffee, then turn it on. Mix it all for about 10 seconds, then start adding the hot/cold water little by little, while constantly stirring it all with the frother.After stirring, start adding cold or warm water to enjoy a warm cup of cappuccino or a cold frappe or milkshakes or any ice coffee of your preference! It comes with a stand in order always to be ready for use.
