Cultivation

Despite great demand as a delicacy (particularly in Sweden, Norway and Finland) the cloudberry is not widely cultivated and is primarily a wild plant. Wholesale prices vary widely based on the size of the yearly harvest, but cloudberries have gone for as little as €10/kg (in 2004). Since the middle of the 1990s, however, the species has formed part of a multinational research project. Beginning in 2002, selected cultivars have been available to farmers, notably 'Apolto' (male), 'Fjellgull' (female) and 'Fjordgull' (female). The cloudberry can be cultivated in Arctic areas where few other crops are possible, for example along the northern coast of Norway.


Uses

When ripe, cloudberry fruits are golden-yellow, soft and juicy, and are rich in vitamin C. When eaten fresh, cloudberries have a distinctive tart taste. When over-ripe, they have a creamy texture somewhat like yogurt and a sweet flavor. They are often made into jams, juices, tarts, and liqueurs. In Finland, the berries are eaten with heated (a local cheese; the name translates to "bread-cheese"), as well as cream and sugar. In Sweden, cloudberries () and cloudberry jam are used as a topping for ice cream, pancakes, and waffles. In Norway, they are often mixed with whipped cream and sugar to be served as a dessert called (cloudberry cream), as a jam or as an ingredient in homemade ice cream. Cloudberry yoghurt— or —is a supermarket item in Norway. In

, Canada, cloudberries are used to make "bakeapple pie" or jam. Arctic Yupik peoples, Yup'ik mix the berries with Pinniped, seal oil, reindeer or caribou fat (which is diced and made fluffy with seal oil) and sugar to make "Eskimo ice cream" or akutaq. The recipes vary by region. Along the Yukon River, Yukon and Kuskokwim River areas, white fish (Esox, pike) along with shortening and sugar are used. The berries are an important traditional food resource for the Yup'ik. Due to its high vitamin C content, the berry is valued both by Nordic countries, Nordic seafarers and Northern indigenous peoples. Its polyphenol content, including flavonoid compounds such as ellagic acid, appears to naturally preserve food preparations of the berries. Cloudberries can be preserved in their own juice without added sugar, if stored cool. Extract of cloudberries is also used in cosmetics such as shower gels, hand creams and body lotions.

, traditional liqueurs such as (Finland) are made of cloudberry, having a strong taste and high sugar content. Cloudberry is used as a flavouring for making akvavit. In northeastern Quebec, a cloudberry liqueur known as (Aboriginal peoples in Canada, aboriginal name) is made.


Nutrients and phytochemicals

Cloudberries are rich in vitamin C and ellagic acid, citric acid, malic acid, α-tocopherol, anthocyanins and the provitamin A carotenoid, β-carotene in contents which differ across regions of Finland due to sunlight exposure, rainfall or temperature. The ellagitannins lambertianin C and sanguiin H-6 are also present. Genotype of cloudberry variants may also affect polyphenol composition, particularly for ellagitannins, sanguiin H-6, anthocyanins and quercetin. Polyphenol extracts from cloudberries have improved storage properties when microcapsule, microencapsulated using maltodextrin DE5-8. At least 14 volatile organic compounds, volatile compounds, including vanillin, account for the aroma of cloudberries.

means "Hill of the Cloudberries" in Scottish Gaelic. Transactions of Camden's Britain (1637 edition) indicates the etymological origins of 'cloud-berry', the plant's name in old Lancashire dialect: 'Pendelhill [in Lancashire] advenceth itselfe up the skie [...] and in the very top thereof bringeth forth a peculiar plant which, as though it came out of the clowdes, they tearme clowdes-berry'. In Norrland cloudberries are known as Norrland's gold. One of the gnomes in ''The Little Grey Men'', a 1942 children's book by "BB" (Denys Watkins-Pitchford), and its sequel is named Cloudberry.


Harvesting on public property

In some northern European countries such as Norway, a common use policy to non-wood forest products allows anyone to pick cloudberries on public property and eat them on location, but only local residents may transport them from that location and only ripe berries may be picked. Transporting ripe cloudberries from the harvest location is permitted in many counties. It was illegal to harvest unripe cloudberries in Norway between 1970 and 2004. Many people still believe that it's illegal to harvest unripe cloudberries in Norway, but the law has been made defunct.
