We just got ourselves our first grinder! It's a cheapie because we're on a pretty tight budget. Kingrinder P0.
I tried 5 clicks from 0, but it wouldn't grind very well. At 10 it actually grinds (takes like 8-10 minutes though!), but I'm not 100% sure if it's grinding fine enough for Turkish. The coffee does get a little bit of foam on top, though! Just a very thin layer. What even constitutes "fine enough for Turkish"? I know it's supposed to be finer than espresso, but does it matter how much finer?

The fresher the coffee, the thicker the foam. I'm pretty sure it's dissolved co2 in an oil matrix just like espresso crema. I haven't made it in ages despite having a pretty copper çevze, but stale preground coffee never gave any foam whereas freshly ground coffee was thick and creamy and delicious as it should be.
