One of my favorite snacks is yogurt. Not only is it great for breakfast, but it's also a good accompaniment to my lunch sandwich and perfect for dessert. The trouble is that I live in a place where yogurt is quite expensive. Sometimes (if I'm lucky) I can buy yogurt for $0.99 a cup, but more often one serving will run me about $1.25.
I'm not embarrassed to say that I was really surprised to hear that things like this Waring Pro Yogurt Maker exist. It lets you make big batches of your own yogurt at home in six 8 ounce or two 16 ounce polycarbonate canisters. To make yogurt, all you have to do is combine the flavors you want with something to make a yogurt culture (which you can find in prepackaged packets containing skim milk powder, sucrose, ascorbic acid, and a lactic bacteria yogurt starter). It has an LED screen and beeps when your yogurt is finished.
The Waring Pro Yogurt Maker costs about $50 at most vendors, meaning that it would pay for itself after making only about five batches of six yogurts each. Not too shabby.
