My grandmother found some old family recipes from pre-independence India. I've never made any of them because they're sometimes denominated in units that no longer exist (a "viss" for example), and some of them are even measured in currency ("buy 10 rupees of x"). Maybe I could try and account for inflation and local prices 100? years ago but...I'm not optimistic.
You might want to talk to the editor of the website India of the Past [0] who collects not only old recipes [1] but also interesting facts on how much money bought how many items [2][3].
