Earlier quoted context omitted.
Baking is very suited to ratios, cooking less so. Bakers commonly talk about percent hydration, which is how much water there is compared to the flour.
My wife makes sourdough, and this frustrated the hell out of me when she started. I asked her what hydration meant, and she said how much water was in it. So of course I told her to do water/water+flour. Nope, apparently it's just water/flour...which doesn't make sense to me, as it allows 'hydration' to go over 100%.
Making a 80% hydration pizza dough? Just measure how much flour you added and multiply by 0.8!
