If you buy a new Aluminum Moka Pot you need to run 3 things of coffee through it and dump it each time to help the oil to seal and season the Moka pot before drinking coffee from it the first time.
Do Moka pots work with hot water?
How do you fill a moka pot?
Remove the basket from the Moka pot and pour hot water into the boiler. If there is no fill line, fill up the boiler to just below the steam release valve. Be very careful when handling the Moka pot after you have filled it with hot water. This is because the metal will heat up very fast.
When should I remove the moka pot from the heat?
It’s best to remove the Moka pot from the heat as soon as the coffee rises into the upper chamber. This is because the residual heat will continue to brew the coffee once it has been removed from the stovetop.
