I was thinking about not doing this one, since it’s not really pastry. However during cheesecake week not long ago, I received several emails pointing out that you can in fact make cheesecake with yogurt cheese. I’m sure there are many more pastry-related uses for yogurt that just aren’t springing to mind at the moment. The important thing is I’ll get to gab about fermentation, which is one of my all-time favorite subjects. Brace yourself for a geeky week!
