Good evening,
I have a very old Polish recipe for piernik (honey cake) which calls for bicarbonate of potash and hirschhorn. Since I've been unable to find these ingredients, I've been trying to find out what I can substitute for them. I've been using baking soda, but the resulting product is not entirely satisfactory. I would appreciate any suggestions you can offer.
Thanks, Helen
