Orehova Potica

Slovenia's rolled walnut cake: dough stretched paper-thin, spread with a walnut and honey filling, coiled into a ring mould and baked

Origin: Ljubljana, Carniola & the Eastern Alps

From the journey of Walnut.

Potica is a rolled cake and the name comes from povitica, meaning something rolled up. Yeasted dough is stretched by hand until it is thin enough to read through, spread with a filling, rolled into a long cylinder, coiled into a fluted ring mould, and baked; cut across, each slice shows a spiral of dark filling through pale dough, and the number of visible turns is how Slovenians judge whether the dough was stretched thinly enough. There are dozens of fillings and the country has counted them: Slovenian ethnographers record more than eighty documented varieties, including tarragon, poppyseed, cracklings, cottage cheese, hazelnut, and honey. The walnut one, orehova potica, is the standard and the festive one, made at Christmas and Easter and for weddings, and it is what is meant when the word is used without qualification. The filling is the technical problem. Ground walnuts are scalded with hot milk or cream and enriched with honey, butter, egg, and often rum and lemon zest, and the mixture must be spreadable but not wet: too dry and it tears the stretched dough, too wet and it soaks through and the spiral collapses into a smear. It is spread warm, which is when it behaves. Slovenia has taken the cake seriously as a national object. Potica was registered as a Traditional Speciality Guaranteed in the European Union in 2021, the country has an official potica day, and a giant potica has been baked for public occasions more than once. Slovenian emigrants took it to the American Midwest, where povitica is a fixture of Cleveland and Kansas City bakeries and is made with a longer, thinner roll.

Ingredients

Dough

500 g strong white flour
10 g fast-action dried yeast
60 g caster sugar
0.75 tsp salt
200 ml warm milk
3 egg yolks
80 g butter, softened
1 lemon, zested

Filling

500 g walnuts, finely ground
250 ml milk or single cream
120 g honey
80 g caster sugar
80 g butter
2 eggs, beaten
3 tbsp dark rum
1 tsp ground cinnamon

To finish

1 egg, beaten, to glaze

Method

Make the dough: mix the flour, yeast, sugar, and salt, then work in the warm milk, yolks, softened butter, and lemon zest to a soft, rich dough.
Knead for a full ten minutes until it is smooth and elastic. This dough has to stretch a very long way and the gluten needs developing properly.
Cover and leave to rise until doubled, about an hour and a half in a warm kitchen.
Make the filling: bring the milk, honey, sugar, and butter to a simmer and pour it over the ground walnuts, stirring to a thick paste.
Let it cool to warm, then beat in the eggs, rum, and cinnamon. It should be thickly spreadable, like a soft nut butter.
If it is stiff, loosen it with a spoonful of warm milk. A stiff filling drags and tears the stretched dough, which is the commonest failure.
Spread a large cloth on the table, flour it, and roll the dough out on it into a rectangle as far as the pin will take it.
Now stretch it by hand from underneath with the backs of your knuckles, working outwards from the middle, until it is about 60cm by 45cm and thin enough to see the cloth through.
Spread the warm filling over the whole sheet, leaving a clear 3cm border along the far edge.
Lift the near edge of the cloth and let the dough roll itself away from you into a long tight cylinder. Pinch the far seam closed.
Butter a fluted ring mould well, coil the roll into it seam side down, join the ends, and prick all over with a skewer so steam can escape.
Leave to rise for thirty minutes, brush with beaten egg, and bake at 175°C for fifty-five to sixty-five minutes. Cool it in the tin for fifteen minutes before turning out, and dust with icing sugar.

Notes

Stretch the dough as far as it will go: the number of visible turns in a cut slice is exactly how Slovenians judge a potica, and a thick roll gives three turns where a good one gives seven or eight. Spread the filling warm and spreadable rather than cold and stiff. Prick the coiled roll all over before baking, or trapped steam will lift the top away from the filling and leave a gap. Grind the walnuts finely but stop before they turn oily. A fluted ring mould, the potičnik, is traditional; a plain bundt tin works. It keeps for a week wrapped and is better on the second day.
