Pour milk into an earthenware bowl or other nonreactive container; let stand in a warm place until thick and sour.
(I put it in my oven with the oven light on. )
When the milk has soured and is quite thick, pour boiling water over it.
Let the mixture stand for several minutes and then pour into a large cheesecloth bag (use double layers); drain overnight or for about 12 hours.
Beat well, adding milk, cream, and salt.
The cheese should end up the consistency of thick apple butter.

Spread schmeirkase on toasted bagels or bread. You can also add spices such as caraway seeds, garlic, parsley, or chives and serve it with crackers or raw vegetables.
