What's the difference between Edmonton and yogurt?

... Yogurt's got culture. Sorry, couldn't resist... And really, that joke is quite equally applied to Cowtown.
OK technically this is penicillin, for some reason they don't have lactobacillis stuffies at Giant Microbes. What the heck. Maybe I should knit one. I followed this very useful article on the cost-effectiveness of making staples at home, courtesy of Nicole, and followed the link to this NYTimes article about making yogurt. I've been meaning to for months, but have never had free time, a gallon of milk, and leftover yogurt in the same point in the space time continuum until now. Now I know what the Slate author meant when she said "The first time I watched this metamorphosis, I felt like a sorcerer." It's true! It's a little strange actually, putting the mix in a warm oven and letting the cultures multiply away in there. It does feel like sorcery. Delicious sorcery. And cheap too, it is half the cost of buying it in the store. Also, no frikin plastic container for my conscience to contend with. A win win win. I'm looking forward to trying my hand at peach frozen yogurt this summer.
