When you open a fresh jar of peanut butter do you only work through one side until it is completely empty then start on the other side?
Or when you get those shallow tubs of hummus does it have to make it back home undisturbed? Then one of the baggers at the grocery store shoves it sideways into the bag completely ruining the symmetry.
Everything gets cut up before a pan gets turned on.
But... onions and mushrooms can easily cook as long as you might take to prep everything else, and they just keep getting better.
No plastic in the microwave. (Ceramics and glass only)
Absolutely. Unless I'm drunk, then a frozen burrito miiiight go in with its wrapper on. Fortunately, alcohol provides near perfect immunity to anything I'd be concerned about while sober.
Range has to be clean before and after cooking.
This is a good rule. Ten years from now when I've finally managed to adopt it, I am certain I will remember you fondly and hope you are doing well - how the time flies when you have a clean range, etc.
Edit to add - can't believe I forgot this. I'll eat any leftovers cold and any fully cooked soup or chili cold too. I just don't care.
Also don't care about reheating leftovers - except rice, I barely like it hot, so cold is a definite no.
I'll add mine here, it's pretty straightforward: TURN THE FUCKING MICROWAVE DOWN YOU NEANDERTHAL!
