Had 2 or 3 cups of yogurt mix left over after filling my yogurt maker and decided to try a suggestion from the comments section of "Homemade Yogurt" by using the crockpot on Keep Warm. I put an inch or two of water in the bottom of the pot, put the mason jars of yogurt-to-be in the pot and walked away. In three hours I returned to find a hideous, rubbery, nasty goo bubbling away in the jars. Now that it's cooled, the glubbery mess is separated from clear fluid in the bottom of the jar. What happened? What did I make? Food chemists? What is that?
