Think of it this way; the last time you cooked this dish there was way too much and youd prefer not to do that again. This would help.with that problem.
I guess it also makes more sense for baking than cooking.
But that's not what this scenario presents. OP was specifically talking about not wanting to leave ingredients around. He's solving a different problem.
All ingredients move together in ratios (got that, totally understand) so I understand HOW this work. What I was commenting on was WHY someone would cook this way. Again, I'm not saying it's wrong, it's just a problem I've never encountered. If I only used 150G of butter and had 100G left, then I have 100G of butter for whatever else I'm cooking.
I'm sure scenarios can be presented for why this is a problem that needs solving (storage space, product expiring, etc) it's never been a way I personally did things.
