Turkish coffee comes in several degrees of sweetness. What Zeynel is ordering is çok şekerli, super sweet. Sugar (or the lack of) is an integral part of the coffee-making process (you don’t put the sugar AFTER it’s in the cup), so it’s important to indicate how sweet you’d like your coffee to be so the formula can be adjusted.
