At school there's a Bake Off amongst the staff for Comic Relief (the results of which shall make up a cake sale). I have never baked  a cake. But how hard can it be? After all, I'm a science teacher, and baking is science for hungry people.

So, armed with Chapter 6 of Ben Miller's excellent "It's Not Rocket Science" in which he talks about the science of making a Victoria sponge, I shall do just that.

No crazy challenges of physical endurance this. No test runs, I shall enter the kitchen with my ingredients, the book, and my wits.

So, if you fancy, do chip in a quid.

Thanks!
