When you do a lot of baking, you pick up odd tidbits of
information that are hard to explain to someone who isn’t as familiar with this
form of culinary creation. You learn when you should substitute whole grain
flours and when you shouldn’t; you know what ingredients to replace in a pinch;
you know if it’s okay to skip a step, if it’s just an unnecessary complication.
And most importantly, you learn how to spot a shitty recipe.
I’m still working on that last one.
