The cheese originally comes from Southern Ostrobothnia, Northern Finland, and Kainuu. The milk is curdled and set to form a round disk from two to three centimeters thick. After this, leipäjuusto is baked, grilled,
Milk and non-bovine mammals varies in composition, but has a similar pH. Initially milk fat is secreted in the form of a fat globule surrounded by a membrane. Each fat globule is composed almost entirely of triacylglycerols and is surrounded by a membrane consisting of complex lipids such as phospholipids, along with proteins. These act as emulsifiers which keep the individual globules from coalescing and protect the contents of these globules from various enzymes in the fluid portion of the milk. Although 97–98% of lipids are triacylglycerols, small amounts of di- and monoacylglycerols, free cholesterol and cholesterol esters, free fatty acids,
