I've heard quite a bit about Mrs. Beeton's Book of Household Management as a good resource for Victorian recipes, though I do admit that I like looking through these books for the household information as well. I was thumbing through a receipt book I procured, which dates back to the 1890's (I forget the exact year at the moment of writing this), and did my usual perusing of various topics it covers. This time, I read a number of items regarding caring for babies as well as the cooking section.
Regarding the latter, I find it interesting how the recipes do actually (for the most part) include measurements for many of the ingredients. I hear over and over that Victorian recipes don't typically have measurements, especially fairly precise ones, but this book does. I'll have to include the actual name, date, and author in a later entry.
Anyways, I looked a little at Mrs. Beeton's Book of Household Management and do hope to try out some of her recipes.
One other resource of note is Historical Foods. I found this while looking to see how others have faired with Mrs. Beeton's recipes. Historical Foods is very helpful, as it uses a variety of sources and attempts to offer modern interpretations while not altering the recipes too much.
