There is no comparison between home-made and store bought yogurt. More than anything a proofer box [0] has made the process better. Author mentions the Brod and Taylor recipe, but not the box. The box is what makes that recipe easy. The "Set it" step is where I find things tend to go awry. The box will hold the temp, which will allow you to control the consistency of the finished product. Also it makes it easier to do larger quantities.
