Early run-up to cheese making?
No, they usually use camel's milk for cheese.
Ferment mare's milk aka airag is the primary form of alcohol in the boonies. If the sun is up, dip your ring finger in the glass and flick some up into the air as an offering to the sky. Mongols don't seem to think the sky is present at night. It isn't polite to refuse airag which tastes like watery vodka with an aftertaste of horse.
mmmmmm mmmm good.
