I've been looking though my great grandmother's cookbook. It's very brittle and some pages are hard to read. It's from 1890 and I was curious whether it was rare so I looked up the title on the internet. I discovered that the same book is available online. Someone has taken the time to scan the pages (not my great grandmother's book of course). It's called the Compendium of Cookery and Reliable Recipes. It has a lot of interesting recipes. Even if you don't like to cook, you should look through the index. Some are very odd (to me at least). There's also some how-to tips.
I noticed there's a recipe for plum pudding Jessaka.
Glenda there's a recipe for mincemeat and one for mock mincemeat in the pastry section. There are soap recipes too. I thought you might want to compare those to what you have.
I clicked on "read online" on the left. Then you can flip through the pages or put in a page number that you want to go to.
