CLABBERED MILK

One of the most healthful drinks in the world is clabbered milk; it is
far better in a way for every one than buttermilk for it requires no
artificial cult to bring it to perfection. The milk is simply allowed to
stand in a warm place in the bottles just as it is bought, and when it
reaches the consistency of a rich cream or is more like a jelly the same
as is required for cheese, it is ready to drink. Pour it into a glass,
seasoning it with a little salt, and drink it in the place of
buttermilk.
