This isn't to slam you, just a tidbit in case you and your wife ever do decide to try teaching her to cook:

Intuition comes from a lot of practice, and external feedback on how close/far you were and how to improve for next time. A professional chef can intuit the temp of a fish they cooked within a degree because they've cooked thousands of fish filets, measured each one with a thermometer to confirm it was cooked correctly, and had other chefs guide them on what to look for (or swore at them when they got it wrong, but maybe don't do that to your wife). They've thrown out hundreds of botched plates. And now they can cook a fish and know with their gut when it's done.

Your wife's first 300 dishes are going to be not so great. And then she'll figure out how to identify what's missing in the flavour, and how to keep from over-cooking the meat, and you get to be there to help her with that, and cheer her on, and call out every time she improves.

Or maybe she finds 300 new textures she hates, but finds 2 meals that don't squick her out to prepare. And that's OK, too.

practice makes perfect! It doesn't take skill to be good at prep and cleaning, just willpower and minimal physical capability. If she doesn't want to cook then you can do it voluntarily. Just seems weirdly old fashioned to have one person do all the cleaning when that is objectively the worst part of cooking
