Just had some stir fried vegetable and adding MSG was magic.
Anecdotally, I’ve eaten dinners cooked by poor rural grandmothers and it’s still pretty oily.
Yeah, I know, but oil is pretty dirt cheap and has been for a while. What poor peasants eat today, or even 50 years ago, could be different from what they were eating in 1850.
I think they may have put on some fancier dishes for guests. My grandmother used to have mantou and a hard-boiled egg for breakfast. And some pickled mustard tubers for flavour.
