I agree with pretty much everything in that video....Except for the way he used the round bottom pot to roast coffee....That pot is too heavy to be tossing around, it also negates the purpose of legs.....He should have stirred it IMO.
I make my coffee in a cast iron skillet, constantly stirring in a small circular motion as I revolve the spoon around the pan. Never stop stirring...I use cast iron because it heats more evenly and has a less chance of burning....I take mine to about the same point he did, start of the second crack when the beans become glossy. Makes a smooth non bitter almost chocolaty brew.....I also have an old Turkish coffee grinder, but I don't use it ....I don't like the fine grind.....Instead I use a 19th century wall mount hand crank coffee grinder that produces a coarser grind.
