This delicious cake (and starter) should be shared with friends, who in turn share with their friends ... and on and on. Thus, often called a "Friendship Cake", it fills the house with an irresistible aroma and makes a lovely present for any Holiday. Although it takes about 3 weeks for the Starter to be ready to use, feeding Herman is very quick and easy. This recipe was given to me by a friend over 30 years ago, and I still enjoy sharing this Herman Cake & Starter (including recipe). Prep. time does not include making the Starter the very first time.
