Residents of Turkey's coastal cities are experts in preparing fish. However, the best of the day's catch is immediately transported to Ankara, where some of the finest fish restaurants are located. Winter is the premium season for eating fish. That is the time when many species of fish migrate from the Black Sea to warmer waters and when most fish reach their mature size. So, the lack of summer vegetables is compensated by the abundance of fish at this time. Every month has its own preferred catch, along with certain vegetables which complement the taste. For example, the best bonito is eaten with garlic and red onions, blue fish with lettuce, and turbot with cos lettuce.
