First I need some curry…uh…okay, do you have salt? WHAT?
Alright, where is the oven? Time to prepare you some amazing lasagna! Where do you keep your noodles? No noodles? I guess I can hack it with potatoes.
…PO-TA-TOES! YOU…WHAT???
Okay nevermind, let me show you why you need to stop spending all your money on survival in warfare and instead fund my school! I can teach you to…uh…tell you about things we have in the future. No, I don’t know how to create any of that. But trust me bro, just give me money. No need to tie me to your trebuchet like that, I’m sure I can remember how to build an airplane somehowAHHHHHHHHHH
You tried.

First I would seek the attention of the local ruler by cooking interesting dishes with modern knowledge.
Then I would ask him to create an akademy. I don’t know the details but I know what can be known. Intelligent people will reinvent the knowledge.
Some side businesses should make enough money that the akademy and thus further development doesn’t entirely rely on the king.
Build cities with public transport and no cars, because there is no car.
Success.
