I found a solution to my last few bags of sour cherries, with the help of Klara over at Paleolicious. She was so kind - not only did she translate her original recipe for sour cherry cake from Hungarian, but also converted it to Paleo in the process! Here is the recipe for the paleo-friendly version with almond and coconut flour.
Not only that, but she recently started a new blog in English. So pop over and say hello! I'm glad I did.
