HI guys, i wanted to know ways of packing al fakher into egyptian bowls. Is it ok to pack overim? Some says it is ok to pack overim for Al fakher. I get less taste, maybe im packing less shisha into the bowl because i left about almost half an inch under the rim. Please help guys, I use four natural coals (non brand, its hard to get here in Thailand), they die out like in 30 minutes. I put the coals on the very edge of the bowl, it taste good for about 20 minutes, then the taste kinda gone. When done, i took out the foil and see, under the shisha still some are not burnt. Any suggestion? Oh and im smoking alfakher orange btw.
