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.

Settling into our first cross-country journey in Turkey many years ago, we were pleasantly surprised by the comforts of Turkish bus travel. The young garson wore a proper uniform and dribbled cologne onto our hands every hour or so. Tea was served regularly, accompanied by one of our early Turkish culinary discoveries, Eti brand pop kek – those unctuous and delicious cakes frosted or stuffed with everything from raisins to chocolate – the Anatolian Twinkie. Call us heathens, but we love them. We’ve tried many traditional Turkish cakes, but none we encountered measured up to the beloved pop kek. That is, until one recent visit to Fatih Sarmacısı, an Ottoman-era shop making our new favorite cake, sarma (the word means “wrapped” or “rolled up” in Turkish).

We recently spoke with travel writer Caroline Eden about her culinary travelogue, Black Sea: Dispatches and Recipes, Through Darkness and Light (Hardie Grant; May 2019). Eden has written for the Guardian, the Telegraph and the Financial Times, among other publications, and has filed stories from Uzbekistan, Ukraine, Russia, Kyrgyzstan, Kazakhstan and Azerbaijan for BBC Radio 4’s From Our Own Correspondent.
