New analysis of f116v, Central Bavarian dialect

[oshfdk]

Of course, we do not know how people spoke 600 years ago. Many medieval words have disappeared but some survived in local dialects until the present day. Furthermore, there is some evidence that he was not a native speaker and probably did not have an university education.

Then unfortunately this theory looks unprovable to me. No amount of indirect evidence like the plausibility of the recipe can replace the direct evidence of actual spellings being used in the XV century. There are just too many possible different ways to interpret a badly spelled and heavily abbreviated short text.
