I'd rather have a baking class that takes an argument for what I want to bake, either bread or cake, and spares me the details of how baking is done. I don't have to know that a preheated oven is one that is at 175 grades etc
And when your oven has a problem with it's heating element you'll have no idea why your cake didn't turn out well. We're supposed to be engineers, right? Learning how things work is good.
