Midye Dolma, or stuffed mussels, are a popular street food in Turkey, sold by vendors from carts along the streets and beaches in lots of cities and towns!
The mussels are cooked and stuffed with rice and herbs. You gently pull the top shell off, squeeze some fresh lemon juice over the mussel and rice mixture, and use the top shell like spoon to scoop it out. I’ll be honest, I’ve never tried them as the thought of mussels just puts me off – but it does look good with all the rice stuffed inside.
They’re cheap, around 50 kurus – 1tl each depending on size, so it’s definitely worth a try. Berkay always goes to the same seller, just across the bridge by the water taxi’s in Calis.
Berkay absolutely loves them, I’m just not brave enough to try!

Try it! I’m sure you’ll like it. I had some once when a friend was having some and I really liked it, but I’m kind of like you, I can’t get over the squeamishness to have some on my own — even though I remember it tasting good!
