Autism affects how senses are processed, and taste is a sense - some autistic people don’t want things that are strong or that vary a lot, preferring consistency instead.

With that being said, it’s not a universal thing, different people are affected differently.

for me autism contains a form of neophobia, the aversion to new things. this food is the edible pendant to a comfy couch, that formed its cushions around you, because you sit in it all day the same.
