What scares me about trying moka is I might enjoy it more than espresso (which I add water or milk to anyway) and obsolete my espresso machine and the effort I’ve gone into mastering the basics!
It's doubtful you will. It doesn't make espresso like an espresso machine does; it's more like coffee. I like them both and like a moka and a french press, they aren't really substitutes for each other.
The coffee is delicious and I don't have to use plastic pods. And I now spend a pittance on coffee
