Station Identification: Cake tastes better on the moon.

“Did you know cake tastes better on the moon? If you went to Earth and had cake you’d be so disappointed. It’d be flat and heavy and solid. It’s to do with pore size and crumb structure, and crumb structure is so much better on the moon. Every cake you make is three kinds of science: chemistry, physics and architecture. The physics is about heat, gas expansion and gravity. Your raising agents push up against gravity. The less gravity, the higher it raises. You might think, so, if lower gravity makes for better crumb structure, wouldn’t the perfect cake be one you made in zero gee? Actually, no. It would expand in all directions and you’d end up with a big ball of fizzing cake mix. When you came to bake it, it would be very difficult to get heat to the centre of the cake. You would end up with a soggy heart.”
