Turkish Coffee - Sand vs Induction vs Gas stove

What is the best heat source for Greek / Armenian / Turkish coffee? Is there a reason to use sand or gas?

Such a great video. Thank you. You have taught me so much.

Lovely relaxed video. I will surely get a hovoli one day, but for now I must be sensible :)

I want to learn making Turkish coffee. So what is the grind setting on your Kinu M47?

'The sand takes twenty minutes to heat up...'
I've never made Turkish coffee in less than 15 minutes on an electric stove without cranking the heat so high the burner glows orange (meanwhile half the people say you have to brew Turkish on low heat which would be like an hour; also seems to be a lot of very different thoughts on when to add the sugar...Does that matter?). Sand's just a lateral move RE: time.
Gonna try the sand method but with fine salt instead. (I don't live in a sandy place and salt's cheaper and more useful to buy in bulk.)
