I just read a book (Trick or Treat by Kerry Greenwood) with a recipe for soul cakes in it that read:

"Tak yr pure wheaten manchet dough and strew thereon saffron and raisins of the sun, cloves cinnamyn sugar if they be hadde, a handful, pounded wel. Knead soft and make yr cakes as many as there be singers."

I'm very glad to have found your more clearly expressed recipe as I plan to try them. Once I perfect that I might try some variations using this as a guide.
