The espresso pots have been popular for more than 60 years. To make coffee in an espresso pot, fill the lower chamber with fresh water up to the bottom of the safety valve.
Fill the filter funnel basket with finely ground coffee. Compress the coffee with a teaspoon, making sure that there is no loose coffee sits around the rim of the basket.
Place the espresso pot on low to medium heat. After the water boils, its steam will start to push the remainder of the water up the funnel. Reduce heat.
When most of the water has left the lower chamber the bubbling sound will become more intermittent. Remove pot from the heat. Wait for the bubbling to ease before serving.
