Perhaps nowhere else is it clearer that as many as one million Syrians have settled down in Istanbul than in the city’s historic Fatih district. The neighborhood is home to the city’s immigration headquarters (Fatih Emniyet), and the backstreets leading up to it are among the most transformed, since Syrians and other new arrivals end up spending hours there, often taking multiple trips to the office to get their paperwork in order. A stroll down the area’s Aksemsettin Caddesi reveals a dwindling number of Turkish markets and a rising number of Syrian ones, a collection of Syrian fast food joints, one Yemeni establishment and one eatery that transports its patrons through time and space, serving up dishes that in the past rarely made an appearance outside of the Syrian home kitchen.

The fatty torik – the Turkish name for a large, mature Atlantic bonito, similar to the little tunny – courses the straits of the Bosphorus and the Dardanelles for just a short period each year in November and December. Yet the people of Istanbul eat it year-round by preserving the fish in a light brine, something it seems they have been doing for millennia – the Byzantines even minted coins with an image of the fish. Making lakerda is more than a means to preserve bonito for the rest of the year, however; it’s part of the city’s culinary instinct. Around 5 a.m. one recent morning in Yenikapı, yellow rubber boots were piled high in front of the one serene spot on the sprawling grounds of the Municipal Fish Auction.
