Turkish is fine like talc. If you press your finger in it, you should see your fingerprint. From the photo, I think you are ok.

that is some damn fine coffee

(sorry i dont know anything about how fine it outta be)

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.

That seems fine. Bear in mind that getting plenty of foam is considered a skill and many people have roughly the same coffee.

Should look like cocoa powder which kind of looks like yours does?

Do you like cardamom in it? I do. I haven't tried it but you can grind seeds (removed from pod) right with the coffee beans.

grind size for Turkish is basically dust or baby powder.

I personally cannot imagine hand grinding Turkish.

Better question...how hot is the sand?

Certainly looks like what they serve me at our offices in Greece and Cyprus.

Are you boiling on the stove? Or just using your coffee machine to run water/steam through it?

The instructions I read described the grounds as pulverized.
