Baking with yeast is the most addictive of pastimes. Once you start, you realize, first, how easy it is, and second, how almost ridiculously satisfying. Partly, this is to do with the feel, the way you sense the dough coming alive under your hands. But perhaps that’s what seems spooky to some people – the thought of live yeast. That’s why I am such a champion of those little sachets of easy-blend yeast: real, live, fresh yeast isn’t hard to use but the sachet stuff seems more approachable at first.
