Most of the product types you're describing didn't meaningfully exist until the 50s (which is why I used that era) as WW2 greatly expanded production of crap food and subsequently led to a wider public introduction. So having family recipes using them from a century or more would be quite odd.

Beyond that, what do you think is more representative of recipes of the past? A selection of hundreds of recipe books with thousands of recipes, or the family recipes of yourself and some acquaintances?
