Why readers need recipe books?

Sometimes readers will leave a comment asking "How much salt?". A weighted question with no answer that I know of. Honestly, I don't know how much salt. My salt adding tactics while cooking is start with less salt --> taste --> add a little more --> taste again -->...repeat steps till equilibrium is reached.... Yes do that and do not dip the same spoon again and again without rinsing and same goes about your finger, ok not the finger maybe.
