This recipe is from an old “Cooking for Today Magazine”, published by Good Housekeeping in 1973. The recipe features in a section of Scandinavian recipes. I have no idea what Rodgrod Med Flod means, but at a guess its to do with the red berries in used in the recipe. Personally I’m not to sure about the potato flour ingredient: I’m sure it’s fine, but….. Would another kind of flour do instead? I expect you've worked out by now that I’ve not made this; I’m posting it for Zaar World Tour 2005. I'm afraid the 'Time to Make' is guesswork.
