it's hell trying to find medieval western european recipes that are 1. somewhat autism-safe, 2. don't contain nuts or other allergens, and 3. aren't some horrible food crime
though you don't have to tell me that restrictions like these completely defeat the purpose
if one is to prepare a historical meal, one must make the conscious decision to eat something completely rank, get overstimmed and die of anaphylaxis and also tastebud poisoning
