I tried making the cheese balls from Das Kuchbuch der Sabina Welserin. First i read the English translation from medievalcookery.com, which sourced it from David Friedman's web site, and then I tried the original version found at http://www.uni-giessen.de/gloning/tx/sawe.htm. . I also found a German redaction at http://www.kochmeister.com/r/65519-kaesekuechlein.html which I used Google translate on. I don't really read German, but to me gebacken sounds more like baking than frying so I went with that option.
250 ml grated mature cheese
250 ml bread crumbs
salt and pepper
I mixed the ingredients and rolled the dough inte balls, ended up with twelve I think. I then baked those at 200 degrees for ten minutes or so. The balls were nice. I had them for lunch with a salad and will probably make them for Nordmark University.
