None of the cnovels I've read so far have any descriptions of food that made me crave the dishes, but that's because I've read only four (and one more in progress). But reading descriptions of food usually makes me hungry.

The only food related thing that comes to mind is Wei Wuxian's use of chili oil during Yi City arc to help the juniors with the corpse poisoning.

That made me realize one thing: as a mexican, the use of chili peppers is ubiquitous, almost everyone loves spicy food, some of them to levels I don't even consider edible.

And of course I have the knowledge that chili pepper is also used in Asian cuisines, but somehow I never even connected the dots that that wasn't always the case. That led me to read an academic book about the history of the chili pepper in China. This books traces the expansion of its use since it arrived from America to the point of becoming a very important part of Chinese cuisine.

This is absolutely one of those things I learn via the ADHD mental process lol
