'Espresso' Maker - Base turned dark, is it bad?
A few days ago I got an 'Espresso' maker made out of Aluminium (one of these).
At the moment I am experimenting a bit with it, but I noticed something strange. The base (the part where you put the water in) turned dark from the inside. Is this normal or bad, maybe even dangerous? Do I need to clean it? If so: How do I clean it?
Best Answer
What you've got there, is a Moka pot. They are unable to produce the amount of pressure that gives the Espresso its character, in particular the crema.
I have owned several, and all of them have had this happen. That has had no impact on the flavour or mouth feel.
