stove top espresso makers
I've got a stove top espresso maker. The strange thing is, sometimes it works fine, and sometimes it doesnt work at all. The steam will just evaporate out of the spout, and the water undeneath just does't bubble through to the pot, meaning there is no or sometimes a small amout of coffee collected in the pot, long after the water has started to boil.
What am I doing wrong?
