Baking analogy at work today. It's been a long while since I've baked, cos I've been helping to sell cakes instead. But due to a temporary shortage of bakers, I was enlisted to do "reverse engineering" baking. Basically, a previous baker baked a cake the customer likes, but didn't leave any recipe for it. Then the baker's gone and the customer wishes to eat a similar cake. So I'm supposed to nibble at their existing cake, figure out what went in there, and try to bake something like it. Good grief.
