Kleinur: Iceland's Twisted Fried Doughnuts

A recipe for kleinur, the twisted fried pastry sold almost daily in Icelandic bakeries and supermarkets, made with sour cream, buttermilk, and nutmeg. Covers dough thickness and cutting, the shaping that pulls one end through a slit in the middle, controlling the oil at 190°C, and the old custom of frying in mutton fat.

Cooking steps

STEP 11 / 5

Mix the egg and sugar

about 3 min

Mixing egg and sugar in a bowl until pale and thick
The graininess of the sugar gone, pale and thick

Beat the egg in a bowl, add the sugar, and mix with a whisk. Mix firmly for 2 to 3 minutes until the graininess of the sugar nearly disappears and the whole becomes pale and thick. Working in air here makes the inside of the finished pastry soft.

STEP 22 / 5

Combine the dairy and flour into a dough

about 7 min

Adding dairy and flour alternately and mixing into a soft dough
No floury bits left; a dough that is a little sticky but comes together

In a separate container, mix the sour cream, buttermilk, and baking soda. Combine the flour with the cream of tartar, salt, and nutmeg. Add the vanilla to the egg bowl, and add the dairy and flour alternately in about 3 portions, mixing with a rubber spatula. The sign is that no floury bits remain and it is soft enough that it is a little sticky to the touch but can be brought together. If it is too sticky, add flour 1 tbsp at a time.

STEP 33 / 5

Roll to 6 mm thick and divide into slender diamonds

about 10 min

Rolling the dough on a floured surface and cutting into slender diamonds with a pastry cutter
Make the diamonds even, 6 mm thick, 2.5 cm wide, and about 6 cm long

Flour the work surface, set the dough on it, and roll with a rolling pin to a thickness of 6 mm. With a pastry cutter or pizza cutter, cut into strips 2.5 cm wide, then divide diagonally at about 6 cm lengths into slender diamonds. If the thickness is not even, the finish is uneven.

STEP 44 / 5

Cut a slit in the middle and pull an end through

about 10 min

Passing an end through the slit of a diamond of dough to shape the twist
Passing the end through the slit twists the middle

Cut a lengthwise slit about 2 cm long in the center of each diamond. Pinch one pointed end and pull it through the slit from underneath, and the middle twists around. Pulling too hard stretches the dough and makes it thin, so keep to just shaping it. Line up the shaped pieces on a floured tray without overlapping.

STEP 55 / 5

Fry in 190°C oil

about 3 min per batch

Frying kleinur golden in 190°C oil and draining them on a rack
Done when both sides are nicely golden

Put at least 4 cm of oil in the pot and heat to 190°C with a thermometer. Gently slip in 5 or 6 pieces of dough at a time, turn them over when the surface turns golden, and fry for about 3 minutes in all, until both sides are nicely colored. If the oil temperature drops below 180°C while frying, raise the heat a little to bring it back. Take out onto a rack or paper towel to drain, and when the heat has eased a little they are ready to eat.

In the bread aisle of a Reykjavík supermarket, bags packed with golden fried pastries are stacked up. Each one is a slender diamond, with one end pulled through a slit in the middle so that it twists around. Icelanders pick at these with coffee on an ordinary weekday afternoon, not a special day. They are kleinur (singular: kleina).

The Nordic countries have several very similar fried pastries, and in other countries they are often made as Christmas sweets, whereas in Iceland they are an everyday snack eaten all year round. The dough is made of flour, egg, sugar, and sour cream and buttermilk, with a faint drift of nutmeg or cardamom. There are only two high points in the method: keep the dough an even 6 mm thick, and fry it in 190°C oil. Hold those two points and you get a fry that is crisp outside and soft inside.

A twisted fried pastry with relatives all over the Nordic countries

Relatives of this fried pastry are found all over the Nordic countries. In Sweden they are klenät, in Denmark klejne, and in Norway fattigmann. The name is thought to come from the Low German Kleinet, meaning a small item or gift. In Denmark they are recorded as early as the 14th century, and in the 18th and 19th centuries the method appeared in Danish and Icelandic cookbooks.

Kleinur first appear in writing in Iceland around 1800, in a cookbook compiled by Marta Maria Stephensen. According to Icelandic Food, a web magazine on Icelandic food culture, what began as a Christmas treat became an everyday snack over the 19th century. Today they are sold singly in bakeries and in bags of about 10 in supermarkets, and it is usual to eat them plain, without powdered sugar or any topping.

Good to know

Long ago, kleinur were fried in mutton fat (tallow). It is a way of frying that belongs to Iceland, where sheep were central to life. Today frying in vegetable oil is common, and some people use lard.

Norwegian fattigmann often includes cardamom, cinnamon, and a very little cognac. Icelandic kleinur also vary in flavoring by household, with some using nutmeg and others preferring the scent of cardamom. The Icelandic Food article writes of the scent of cardamom filling the kitchen while frying as a memory of this pastry. With either spice, a very small amount is enough. Too much makes the spice too assertive and hides the plainness of the fried sweet.


Ingredients (makes about 18)

Flour, egg, sugar, sour cream, buttermilk, nutmeg, and cardamom used for kleinur

This mix takes the recipe published in the Icelandic English-language magazine Reykjavík Grapevine (about 50 pieces) and reduces it to one third, an easier amount to fry at home. Cup measures have been converted to grams and ml.

Cream of tartar is a white powder, potassium hydrogen tartrate, which leavens dough when used with baking soda. It is available at baking supply shops and online, but if you do not have it you can substitute baking powder. Nutmeg and cardamom are both found in the spice aisle of a supermarket. Cardamom gives a fresh, Nordic scent, so trying it the second time should be fun.

Tip

Buttermilk is not always easy to find. Mixing lemon juice into milk and letting it stand a little produces body and acidity that stand in for buttermilk. The acidic dairy reacts with the baking soda and has the job of making the dough puff up softly.


How to make kleinur

Making the dough takes about 10 minutes, rolling and shaping about 20 minutes, and frying about 30 minutes. Frying all the shaped dough together lowers the oil temperature easily. Fry 5 or 6 pieces at a time, a few at a time.

Caution

Frying oil gets very hot. Do not leave the stove while frying, and if the oil gets too hot and smokes, turn off the heat at once. When adding dough, slide it in gently from close to the surface of the oil, and watch for burns from splatter. This sweet contains wheat, egg, and dairy.

Tip

If the oil is too cool, the dough soaks up oil and turns heavy. If it is too hot, the outside burns while the inside stays raw. Fry the first piece as a test and break it open to check that it is cooked to the center, then fry the rest, and you will not go wrong.

A traditional tool for even shapes

In Iceland, a dedicated tool for cutting kleinur dough, the kleinujárn, has been used. It is a small wheel-shaped tool that is rolled over the dough to cut it. A pastry cutter does the same job, and a pizza cutter is quite enough if you have none.

When shaping, what to watch is making all the diamonds the same size and thickness. It makes the frying times match, and they line up neatly in a bag. Cutting against a ruler keeps the shapes even even when you are not used to it. The first few twists may be awkward, but by the time you have made 10 your hands remember.

With coffee, while still warm

Let them cool a little after frying and have them with coffee while still warm

It is said to be best eaten after cooling a little from fresh out of the oil, while still faintly warm. In Iceland, the standard is to eat them plain, without any topping, with black coffee. The outside is crisp and toasty, the inside moist and soft, with a faint tang of sour cream and the scent of nutmeg left behind. If you want to add sweetness you may dust them with powdered sugar, but it is not a way you often see Icelanders eat them.

Storing in a dry place is the way to handle kleinur. When they absorb moisture, the crisp texture of the outside is lost. If you want to make one more Nordic snack, Denmark's open-faced sandwich, smørrebrød, shows a different face of the Nordic table from coffee time.

Frequently asked questions

Kleinur cooling on a rack

The dough is too soft to roll.

Use plenty of flour for dusting, and add flour 1 tbsp at a time. If it is still sticky, wrap it in plastic and rest it in the refrigerator for about 30 minutes to make it easier to handle. Adding too much flour makes the fry hard, so add it a little at a time.

Can I make it with baking powder only?

You can. Instead of baking soda and cream of tartar, mix 2 tsp baking powder into the flour. The rise and flavor change a little.

The inside is raw after frying.

The oil may have been too hot so that only the outside colored first, or the dough may have been too thick. Keep 190°C with a thermometer and make the thickness 6 mm. Pieces with a raw center will cook through if fried again in 180°C oil for about 1 minute.

I want to try frying in mutton fat.

Mutton fat is hard to get, so mixing a little lard into the frying oil gets closer to the old-fashioned richness. Vegetable oil alone also fries up well.

How long do they keep?

They are best on the day they are fried. Store them in a dry place and finish them soon. This article gives no storage days, because no reliable basis for them could be confirmed.
