Last weekend I made some Viking-style snacks for another SCA vigil, and tried some new stuff this time. I made a big batch of skyr, and needed to make use of it, so I mixed some skyr with honey, then added some little dried prunes and hazelnuts fried in butter. This worked out really nicely, and includes ingredients common in the archeological record. It was quite good with the barley flat bread. I'm thinking it would be even better filling the barley pancakes. Hmm.
The other new one was some oatcakes, which were just butter, honey, oatflour and rolled oats (and maybe a bit too much salt). Baked until cookie like. They were a lot like simple (salty) oatmeal cookies. Good with herring.
