Here is another delicious Turkish sweet. It is made from ripe quince, which is only available for two or three months in autumn. This ayva tatlısı came from Sakarya Tatlıcısı (here) in Beyoğlu, and it is the real deal. Other places will add colorants, making it look like this. The white topping is kaymak, which is kind of like clotted cream, but better. Real kaymak is made from water buffalo milk.
