Baking vs Cooking?

I think it is a general trend. Baking is more difficult than just cooking, and doesn't lend itself as well to improvisation. If you're off a little on the proportion of ingredients, the character of your baked goods can change completely. There's a lot less flexibility in baking than there is in an ordinary recipe.

Cooking is an "Art". Baking is a "Science".

Most Chefs don't want to measure, adding a bit of this, a bit of that, then season to taste. Baking you have to measure and follow a recipe or else it won't turn out right.
