Gamalost is a traditional cheese made from skimmed cow's milk. The cheese has a mold-ripened rind; its texture is dense, granular, and chewy, the aromas pungent, while the flavor is sharp. It's also rich in protein and has a fat content of only 0.5 to 1.0%.
The cheese is traditionally aged from 1 to 6 months. In order to make it, an acid is added to skim milk, causing it to sour. The fermented solids are then pressed into molds to create the circular shape. Later on, the cheese is hand-rubbed with mold and left to age.
It can be stored for a prolonged period of time without refrigeration, which is why it's been produced in the past when there were no methods of refrigeration. Gamalost should be cut with a hollow blade cheese knife due to its dense and granular texture.
