In Turkish coffee culture, it's common to leave the coffee grounds that settle at the bottom of the cup after you've finished your coffee. Drinking the coffee grounds is not a customary practice, and the grounds are typically not consumed.
If you're served Turkish coffee and notice coffee grounds at the bottom of your cup, it's best to leave them undisturbed. Instead, you can enjoy the flavors and aromas of the coffee that you've already consumed. The coffee grounds are typically reserved for fortune-telling or reading, adding a sense of mystery and intrigue to the coffee-drinking experience.
