We were wondering about old-style recipes for cakes a while ago, inspired by some quite old (Art Deco) tableware, which had rather small plates for the cakes (or whatever else would have been served on them).
So I did as you do when wondering about stuff like that - I went into the Internet Archive and the Open Library and had a rootle around for recipe books from the end of the 19th century.
One of the books I came across was a really curious example, with a lot of advertisements, and a lot of recipes, but not just for cooking, no, for about everything from dyeing wool to dyeing hair to cleaning stuff to baking to curing sick horses. It's called the Brill's Family Recipe book.
I'm not sure if I will actually try one of the cake recipes - but it was definitely very amusing to leaf through this curious mixture, and it does give an impression of what was considered important or necessary recipes back then.
