I didn't know what a hermit was until I found this recipe in a very old cook book, which had been put online as a part of Project Gutenberg. I downloaded Things Mother Used to Make by Lydia Maria Gurney here.
Hermits are molasses cookies with chopped raisins in them. I have a favorite molasses cookie recipe, but never thought to add raisins. What a great idea!
It was also so fun to look at a cookbook from someone who lived in a very different world than I did.
