Oreovki: Balkan Walnut Sweets
In the Old Čaršija in Skopje, after a lunch of kebapi and tavče gravče, I was just looking for something small to eat on the go. On one sweets stall lay pieces that looked like a lump of ground walnuts someone had bent into a horseshoe - no dough in sight, no glaze, just walnuts holding themselves together somehow, and from the counter you couldn't tell what.
Oreovki (Macedonian: ореовки), also known as orasnici, are a sweet made from walnuts, eggs, and sugar without a single gram of flour: a mixture of finely ground walnuts is shaped into a small horseshoe and coated in coarsely crushed ones, so there's walnut both inside and on top. It's not a Macedonian invention - the whole former Yugoslavia bakes the same sweet. In Macedonian cuisine it belongs with the čaršija, with coffee, and with one confectionery that built its name on it.

One Horseshoe, Two Names, and Relatives Across Half the Balkans
The name brings a small complication right away. Recipe websites write ореовки, from орев, walnut, but the confectionery in the čaršija sells you орасница, from орас, another word for the same nut (and noticeably more common on Macedonian websites) - and one recipe site solved the problem its own way, heading the recipe with both names at once. One sweet, two names, both simply meaning "walnut" - and that's the whole description, because there's really nothing in them but walnut. The family is broad and, to be fair, shared: the whole former Yugoslavia knows orasnice - in Serbia they're a classic celebration sweet, and they're baked in Bosnia and Croatia too. The recipe is the same everywhere; some people whisk just the egg whites, others use whole eggs, and Macedonian recipe sites list both, treating the whole-egg version as a variant rather than the rule. Bulgarian cuisine has its own orehovki, which stick to the egg-white version. Anyone looking for a spin-off of small Turkish sweets is looking in the wrong place: the Turkish and Bulgarian kurabiye cookies have butter, flour, and an Arabic name, and with baklava, which a few travel sites compare them to, they share only the walnut and the peninsula - you won't find layers of dough or syrup here.
A Confectionery from 1978 and a Sweet Without a Date
Nobody has written the history of oreovki; Macedonian and Serbian websites both file them under starinski, grandmother's recipes from the days of the shared state, and that's where the dating stops. The only fixed date belongs to the confectionery famous for them: Rigara in Skopje's čaršija, opened in 1978, built its name on orasnici and still makes them by hand today. A report on the confectionery also admits that younger Macedonians reach for other sweets these days, and orasnice remain a dessert nobody forgets, but nobody lines up for it.

What Oreovki Are Made Of and When to Have Them
In oreovki the walnut plays two roles at once. Finely ground, it forms a mixture with the eggs and sugar that's held together only by the egg as a binder, and coarsely crushed, it forms the coating each piece is rolled in before it's shaped into a horseshoe; butter, flour, and baking powder play no part in any of it. Long drying then decides the texture: the coarse-walnut coating dries out crisp, while the ground-walnut center stays soft. By all accounts, what matters most is the walnuts themselves.
Oreovki go with coffee, they're sold one at a time from the window, and they keep well in a box, which is why tourists take them home from the čaršija as a souvenir. Look for them under the popular name орасници rather than ореовки; it's the same thing, and the seller won't bat an eye.

A Handheld Dessert
I got mine at the Rigara confectionery (see Where to Eat in Skopje) and ate them on the go. I expected something dense from the walnuts, and instead it cracked and crumbled at the first bite; that crispness surprised me the most, with a soft center underneath and a purely nutty flavor, sweet just enough that the walnut didn't get lost.
