YAR-SALE (Russia) • The tundra at dusk looks like the open ocean, waves of shades of blue, grey and white.
Indigenous reindeer herders traverse this terrain, eking a nomadic living out of the barren land. The biting cold this time of year keeps their provisions perpetually frozen, but they sometimes lack the time - or the firewood - to cook them.
So, when Mr Mikhail Khudi, a reindeer herder, is hungry, he likes to take a bit of raw, frozen fish or reindeer meat from his sled-top pantry and dunk it in mustard before it disappears, chewy then creamy, in his mouth.
Travel thousands of miles across Arctic Siberia - from the oil-and-gas heartland on the Yamal Peninsula just east of the Ural Mountains, to the nickel smelters of the lonely city of Norilsk, to the gulag-haunted banks of the Kolyma River as you approach Alaska - and you will encounter Mr Khudi's snack: stroganina.
It is raw, frozen fish or meat, shaved thin with a sharp knife so that it curls off the blade.
Hurry - you have to eat it before it thaws for the best flavour and texture, dipping the frozen shavings into a salt-and-pepper mix or your favourite sauce, then chewing lightly as they melt on your tongue, like a popsicle version of sashimi or carpaccio.
You will rarely find stroganina on the menu in Moscow. But one is convinced this is one of Russia's greatest delicacies.
In Siberia, you will find people who are stroganina connoisseurs, critiquing the mustiness of frozen whitefish from smaller lakes or praising the clean leanness of the catch from the Gulf of Ob.
"I'm used to my Ob kind," said Mr Dmitry Kuybin, who fishes on that gulf, a 965km-long estuary along the eastern coast of the Yamal Peninsula that flows into the Arctic Ocean.
"This lake stuff" - preferred by reindeer herders, he said - "tastes kind of mossy."
For what to dip stroganina in, the possibilities are endless.
Ms Nellya Motysheva, who also lives on the peninsula, plans to collect her recipes in a book. What she calls "mum's sauce" is vegetable oil, mustard powder and reindeer blood.
The Russian Arctic looks remote on the map, but more than one million people live here - far more than in the polar regions of Western Europe and North America.
From the Bolsheviks' forced collective farming to the gulag labour camps to the chaotic collapse of communism, outside forces beyond local control have shaped the lives of its residents.
Now, places like the peninsula are synonymous with Russia's rapid development of the oil-and-gas reserves in its northern reaches.
Global warming is threatening traditional ways of life. The receding sea ice is turning the region into a theatre of increased trade and intensifying geopolitical competition.
"Nevertheless, we've kept our passion for our traditional food," said Ms Zoya Safarbekova, director of the Yamal District Museum in the town of Yar-Sale near the Gulf of Ob, after ticking off the external shocks that have befallen her indigenous Nenets people over the last century.
"In November, the freezing cold begins and that's it - you know you must eat stroganina, " she said.
The name of the dish comes from the Russian word "strogat", meaning "to whittle", as a carpenter would. It is distinct from the less refined rubanina - from the word for "to chop" - which is a frozen fish pounded to bits with an axe.
The best stroganina, Yamal residents say, is produced when it is chilly outside - no warmer than - 29 degree Cs. That temperature flash-freezes the fish or reindeer meat and locks in the flavour.
It was relatively warmer - about -20 deg C - when Mr Kuybin went about 50km out of the Yamal village of Salemal as he checked his fishing nets.
Mr Kuybin, who works with his wife for the Salemal fish plant, did not bother to wear mittens or gloves. He donned rubber boots, camouflage pants and a hooded reindeer-fur cloak.
The catch was meagre this time. He lay a pike straight on the ice before it froze, guts and all, to allow for even and well-curled strips of stroganina.
He later acknowledged that eating frozen fish when it is freezing cold outside sometimes makes him even colder, but he says he enjoys it anyway. "It's our own thing, you know," he said.
The Yamal district put on a stroganina festival last December in the town of Yar-Sale, just north of the Arctic Circle, with a population of about 6,000.
The district flew several Russian culinary celebrities to the regional centre of Salekhard and sent tundra-grade jeeps to take them on the five-hour drive over the frozen Ob.
Like many Arctic towns, Yar-Sale is accessible by ice road in winter, by boat in summer and only by helicopter in spring and autumn.
There was a ball, cooking classes and a stroganina-making competition with separate reindeer and fish stages judged by local officials and celebrity visitors.
The hardest part of the stroganina process seemed to be peeling the skin off the frozen fish. The best slices emerged thin and curly, shaved by slicing downward, rigid tail held tight.
If the feel of the frozen fish on the tongue recalled a light sorbet, the frozen raw reindeer was like a rich ice cream. In both cases, the flavour of the meat hits you as it thaws.
Three of the competitors brought along reindeer blood, a traditional stroganina dip. It tasted like the essence of rare venison steak - gamy, sweet, salty and smokey.
Young women carried the stroganina to the town square, where residents sampled the competitors' handiwork and cast their votes.
Children played on a slide hewed out of ice and around ice sculptures of the Taj Mahal, the Eiffel Tower and the Parthenon.
The celebration was a reminder that Russia's underground Arctic resources, made more accessible thanks to global warming, have created a cascade of wealth even as reindeer herders, hunters and fishermen complain of pollution and disruption from new oil wells and gas pipelines.
Ms Motysheva, who makes the blood-and-mustard dip, won the residents' vote competition.
Her book of stroganina sauces will be called Our Future Is With Our Ancestors. She said the dish was rooted in the Nenets' nomadic past, a time when they could only survive on frozen raw meat in the barren tundra.
"If we start forgetting what we once had, we won't have a future," she said.
