Select a quality mixture, suitable for making coffee for Moka. Fill the boiler to the lower level of the safety valve, without exceeding it and using fresh water, possibly poor in limestone. | Fill the filter generously, without pressing the coffee powder, forming a small wedge and avoiding dust leakage on the boiler edges. Close the coffee maker, vigorously screwing the collector onto the boiler and place it on the stove. | The flame must never wrap the coffee pot, but remain inside the bottom of the coffee machine, in order to allow an extraction in an appropriate time and not too quickly. As soon as you start to feel the typical Moka gurgling, the coffee is ready and you will need to immediately turn off the fire. | Never let the excess coffee boil: this would burn it, compromising its success and making it too bitter. Enjoy the hot coffee, just ready, reminding you to mix the contents of the collector: the coffee extracted at the end, in fact, is less full-bodied than the leached at the beginning of the boiling. |
