This recipe first appeared in a letter-to-the-editor in the London Monthly Magazine in 1799. In this letter, the author explains the benefits of making a cake with potash, instead of yeast! The result is a light, fluffy cake that could be made in minutes (and was also beneficial since yeast wasn't always readily available). In the following video from Jas. Townsend and Son, Inc. we'll learn how to make these delicious cakes. Follow along with the video (we've also found a similar, written recipe here) and let us know if you give it a try in the comments below! We'd love to know what you think of them.
