I have now made a Herman cake twice with sourdough starters given to me by friends and I'd like to make it from scratch.
Does anyone have a recipe for the sourdough starter used with Herman cakes, please?
(In case you haven't heard of it, a Herman cake is (I think) also known as a Friendship cake, and there's a "feeding" palaver, a bit like with a ginger-beer plant (not that I have firsthand experience of one of those) and you are meant to end up with four times as much starter as you need and to give three portions away.)
I have various sourdough recipes in bread cookery books, but it is specifically the recipe for the herman cake starter that I'm looking for.
