A regular volunteer, Chris Middleton, brought me a 1909 Presidential Cookbook.
It's in pretty bad shape, as you can imagine. But, you can still read the recipes.
Right away, I turned to page 111, where I found several recipes for tripe. Yipe! Tripe! It appears that to make tripe edible you have to cut it into small pieces and boil it for -- literally -- hours.
The cooks who put this book together have no qualms about tripe, and no qualms about using plenty of lard and butter. Everything's better with lard and/or butter.
You can tell they had their priorities straight: They included four chocolate cake recipes.
