The wonderful thing about food is that it's always changing. People shit on stuff for not being "authentic" but frankly I think it's delightful how different traditions come together to play. Mixing and matching until the local food reflects the available ingredients and preferences of the populous.

I mean I make a mean lemon tofu which is a derivative of lemon chicken which is a derivative of a Cantonese style that was adapted for churning out cheap and appealing food so migrants could work at takeaway stores and get visas.

Food tells a story, wherever you have it and however you have it. Appreciating that is imho the more joyful approach than trying to fix it in time.
