I, too, have a similar grinder and I, too, collect the stuff in the front
But instead of tossing it, I scoop it into the basket of my steam toy
"pseudo-espresso" maker, knock it on the counter a bit to settle and
distribute the powder-fine coffee, tamp it firmly with a bit of rotation and
a little twist -- and get really sweet shots from it. This is the only way I
currently have of getting a grind fine enough for anything like espresso. My
little steam machine can't push but something in the order of 1 to 3 bars,
but it can extract reasonably well from this fine grind.
I've made brew with the Moka pot using these fine grinds, too, put more
comes through the basket than I care to have in my cup.
