Prästost

Prästost is a Swedish cheese with historical roots in Sweden's one-time custom of paying tithes with agricultural goods including milk. Milk spoils easily so most farms instead produced a small eyed cheese that had its curing process started by mixing in a small batch of fermented curds. This was common practice from the 16th through 19th centuries. Today, this style of cheese once produced in churches across Sweden is factory-made from pasteurized cow's milk. Prästost is marketed under the trademark Präst, which was registered in 2001 and is owned by the company Svenska Ostklassiker AB, a subsidiary of Svensk Mjölk.
In Sweden, Prästost is produced by Arla Foods, Skånemejerier and Wernersson Ost. It is also sold at Lidl under Lidl's own brand name Matriket.
