I realize I'm pulling this thread out of the deep freeze, but I make my yogurt in a crockpot. I have about 2% involvement in the process, and the crockpot does all the rest! I strain the yogurt through cheesecloth -- I tried the coffee filters but they clogged up and didn't let much whey through. Nielsen-Massey makes a vanilla powder that I love to put in with yogurt and muesli, but fresh blueberries are just a little bit of heaven too.
