A classic liqeuer recipe found on norsktradisjonsmat.no
A lovely liqueur made by many for Christmas in Norway. This recipe was submitted by May Britt Bischof from Onsøy Associated Country Women. She writes that this is an old recipe from Onsøy, which is taken from the book “Drink from Østfold”, published by Østfold Associated Country Women.
The same recipe can be used with other types of berries such as blueberries, rowanberries, red currants and black currants – Ted
750 g [1,65 lb] blackthorn berries
Vodka/unspiced liquor, 40-60%
4 dl [0,8 pt] sugar
 Put the berries in a Mason jar or similar and pour in liquor / vodka 40% (or 60%) until the berries are covered. Leave the glass for a minimum of one month (preferably two) before the alcohol is sifted from the berries. Store the alcohol in a bottle.
 Pour the berries back into the jar and pour in the sugar. Shake often until the sugar has dissolved. Leave the jar until the berries have shrunk. sift the sugar syrup from the berries and mix with the spirits. Pour the liqueur into bottles and store them cold.
 The blackthorn berries should preferably have had a night of frost before they are used, but one can cheat by putting them in the freezer over night. This goes for rowanberries too.
