Tzatziki or Ketchup and Mustard? How Greeks Really Eat Gyro
If you think tzatziki is served on every gyro in Greece, well, you're wrong, and you're about to be mind blown. Ask someone in New York, Melbourne or Toronto what goes on a gyro and the answer comes back instantly: tzatziki. Plenty of Greek families abroad would say the same, and fair enough, since that cool, garlicky yogurt sauce is what most Greek restaurants overseas spoon into every pita.
Now walk into a gyradiko in Thessaloniki and listen to the orders. You will hear a lot of “ketchup and mustard”, said together as one request, as if they were a single condiment. Nobody blinks. In much of northern Greece that pairing is simply how a pita gyro is dressed, and the visitor who expected tzatziki is the one who looks surprised.
So which is right? Both, and neither. Gyro in Greece is less a fixed recipe than a family of local habits, and the sauce is where those habits show most clearly.
Thessaloniki style: the ketchup and mustard city
Thessaloniki and the rest of northern Greece take its gyro seriously, and northerners will happily tell you it is the best in the country. The classic pita there comes with sliced tomato, onion, a handful of fries and a squeeze of mustard, with ketchup alongside it in most modern orders. If you want tzatziki, you usually have to say so, because it is not assumed.
The bread matters too. The standard is a thick, soft, well-oiled pita warmed on the griddle, but many shops also offer a thinner pocket-style pita, a large crisp “Arabic” pita, or plain sliced bread, which is a popular choice in the north. Locals even call the wrap a “sandwich”, and keep the word gyro for the meat itself. Northern pitas also have a reputation for being generously filled, and Athenians who order one for the first time tend to notice.
And when a Greek is really in the mood, there is no need to choose sides at all. Ketchup, mustard and tzatziki, all three in one pita, is an order you will hear more often than purists would like. It should not work. It absolutely does.
Crete and the rest of the map
Head south to Crete and the sauce changes again. Many Cretan souvlaki shops skip tzatziki and finish the pita with a spoon of thick strained yogurt instead, plain and tangy, letting the pork and the island’s olive oil do the talking. Some stands also offer a “Russian” style sauce made with mayonnaise and pickles, and in towns like Chania you will meet shops that leave the fries out entirely.
Corfu has its own habit of adding a red tomato sauce, and across the country the menu has grown well beyond the classics. Tirokafteri, the spicy whipped feta dip, is a common upgrade, along with mustard sauces, yogurt sauces blended with honey or mustard, and house “sauce” that tends to be some mix of ketchup and mayonnaise. Many shops finish the pita with a pinch of paprika or salt and oregano over the fries.
Even within a single city the rules bend. Some well-loved Athens souvlaki joints serve plain yogurt rather than tzatziki, and every neighbourhood has its regulars who swear their local spot does it the proper way. Tzatziki is probably still the most common choice nationwide, but it is a favourite, not a law.
So how did tzatziki become the go-to sauce for Greeks abroad?
Much of the answer is in Chicago. Greek immigrants there were already serving gyro in the 1960s, and in the 1970s a few Greek-American businessmen began mass-producing ready-made cones. Peter Parthenis started what became Grecian Delight around 1973 and 1974, and Chris Tomaras founded Kronos in 1975, making the first pre-formed beef and lamb cones. Frozen cones could be shipped anywhere, so a diner from Atlanta to New York could serve exactly the same gyro, and tzatziki came as part of the package. Grecian Delight began producing it in 1975, and it became the standard American topping along with tomato and onion.
The pairing also simply works. A cool yogurt sauce with cucumber and garlic cuts through rich, spiced beef and lamb. For non-Greek diners it was an easy introduction to Greek flavours, and for Greeks abroad it was a taste they already knew from home.
So if you grew up eating gyro abroad, tzatziki probably feels like the only right answer. Back in Greece, the sauce still depends on where you're standing, and that's half the fun.
From Asia Minor to every street corner
The technique behind gyro is older than the word. Stacking slices of meat on a vertical spit and carving them as they roast took shape in the Ottoman world in the nineteenth century, most famously in Bursa, and it is the same idea behind Turkish doner, Arab shawarma and even Mexican al pastor. They are cousins, each adapted to local tastes.
The method came to Greece with the refugees of Asia Minor after the 1922 catastrophe and the population exchange of 1923, when more than a million Greeks were uprooted from Anatolia and resettled in cities like Athens, Piraeus and Thessaloniki. They brought their kitchens with them. In the years after the Second World War, spit-roasted meat in pita became a cheap, filling street food, and by around 1970 it was firmly established as Athens fast food.
For a while the dish went by “ntoner”, borrowed from the Turkish döner. That name drew criticism for sounding too Turkish, and the Greek word gyros, meaning “turn”, took over. It is a neat translation, since döner itself comes from a Turkish verb meaning to turn. Along the way the Greek version settled on pork as its signature meat, which set it apart from its neighbours.
Gyro is the meat, not the wrap
Here is the detail that trips up most visitors. In Greek, gyros is the meat: the thin, crisp shavings carved from the turning spit. The wrap is a pita gyro, meaning gyro in pita. Order a merida, which literally means a portion, and you get the same meat on a plate with fries, tomato, onion, a little salad, pita on the side and a sauce, ideal when you are sitting down rather than walking.
The meat itself is different from what many people know abroad. In Greece, gyro is overwhelmingly pork, with chicken as the everyday alternative. The compressed lamb and beef cone familiar from diners in the United States is rare at home, and if you see beef on a Greek menu it may well be labelled ntoner or kebab rather than gyro.
Just because it is wrapped in a pita does not make it a gyro. Look at the person next to you at the counter. Their wrap may look exactly like yours, but inside it could be cubes of pork grilled on a skewer, which makes it a souvlaki pita, not a gyro. It could just as easily hold soutzoukaki, a spiced minced-meat patty shaped long and narrow rather than round like a burger, or loukaniko, Greek sausage. Same bread, same tomato and onion, completely different meat.
So gyro is the meat, not the wrap you happen to be holding. That is also why menus list a gyro merida, or gyro plate: everything that goes into the wrap, only more of each, spread out on a plate.
To make all this even more confusing, Athenians tend to call every one of these variations and combinations “souvlaki”, but more on that later.
How to order like a local
Say “me apola”
The magic phrase is “me apola”, with everything. You get the shop’s standard fillings, which in most of the country means tomato, onion, fries and the house sauce. Just remember that “everything” means tzatziki in Athens, mustard and ketchup in Thessaloniki and yogurt in much of Crete.
Adjust the sauce
To change things, use “choris”, without. “Choris kremmydi” drops the onion, and “choris tzatziki” skips the sauce. To add something, ask for it by name, “me tzatziki” or “me moustarda kai ketsap”, and nobody will judge you for asking for all three. Pork is “choirino” and chicken is “kotopoulo”.
Gyro, souvlaki or kalamaki?
Gyro is carved from the vertical spit. Souvlaki is cubes of meat grilled on a skewer, which Athenians call kalamaki, “little stick”. To make it more confusing, in Athens and much of the south people often say “souvlaki” to mean any pita wrap, gyro included, while in Thessaloniki souvlaki means the skewer. This kalamaki or souvlaki label is another Greek civil war in itself. When in doubt, point at the spit or the grill. Everyone understands that.
Whether your loyalty lies with tzatziki, with ketchup and mustard, or with all three at once, the best gyro is the one eaten warm, standing up, with a napkin that never quite does its job. Ready to try making them yourself at home? Check out our GetGreece Recipes.
