Crowdie
Crowdie is a type of soft, fresh cheese made from cows' milk, traditionally from Scotland. The cheese was traditionally made for domestic use by crofters and smallholders in the Scottish Highlands and Islands, using milk from the family cow. Its origins date as far back as the Viking era and possibly even earlier to the time of the Picts. Crowdie is a variety of lactic cheese. These rely primarily on the action of the bacteria converting the milk lactose to lactic acid to create curds. When the milk acidity becomes high enough, the milk will coagulate even without the use of rennet.
