Delicious that cottage cheese in Turkey. It took some effort to find out what cökelek means. Because you read it pretty often. It is a delicious salt-free cheese like cottage cheese or the Italian ricotta.
In this shop, besides the cheese, the better olive oil, olives and some other specialties are sold. You'll find this store in Kariaport, with the escalator down and right around the corner. You can also eat a delicious sandwich here.
