Another new recipe: http://www.myitaliansmorgasbord.com/2012/07/27/mixed-seeds-knackebrod-swedish-crackers-for-the-daring-bakers/ from a great website/blog.
It is a yeast dough but rolled very thinly and baked immediately. I tried plain ones with caraway and nigella seeds in the dough and the more coloured ones had an egg glaze into which I rolled some more seeds. I think these look better and have a great flavour. Suspect cumin seeds would be another good one. Easy and quick to make and very good with cheese. Would make a great Christmas gift.
