The recipe I tried said to bring the milk up to 180 degrees F. it
was was regular processed milk. The purpose of this is to kill any bacteria
that may be floating around, ready to multiply.
If using powdered milk you can merely it with warm (110-120 degree)
tap water.
If using raw milk, bring it to a full boil, this is not so much to
kill bacteria, but to destroy the active antibodies in the milk. Failure
to destroythese antibodies will result in a very runny yogurt.
