would there even be old street maps of Tübingen from the late 1700s showing bakeries?
how would i found out what they made??
no, im not doing this, I'd have to like, figure out how to access historical documents in a german city I've never been to just to begin to proceed
this way lies madness
i don't sleep enough and my brain starts raising Important Questions
in all seriousness, how would we even go about determining certain things like this?
I'm sure, for example, if we have diaries and personal accounts from/about historical figures we can glean some information from them, but we're probably never going to find out the answers to trivial but tantalising questions
