When Michael Ruhlman posted a buttermilk dinner rolls recipe on his blog, ruhlman.com, I just had to try it. I'm always on the lookout for a good roll recipe. The problem is that I can't find buttermilk here in Tokyo. I've often substituted half yogurt and half milk whenever a recipe calls for buttermilk so I thought I'd give the recipe a try. Another problem cropped up when I started assembling the ingredients: I had only about 100 grams of yogurt. But wait, I had some cream left over, that makes about 200 grams of liquid now. Looking in the fridge, I had milk, but only low fat. Well, let's just make do and see how the bread turns out.
