Several years ago, my husband and I went to a Christmas market in Cologne, Germany. One of our favorite foods we ate at the market was labeled as simply "knodel (which I discovered meant, "dumpling") and cabbage." It came served in a bowl, tasted like spaetzle, and had cooked cabbage and what appeared to be sour cream(?), which melted a bit and made a nice sauce. It was clearly doused in butter. It was delicious. Since then, I've tried to find out if this is a "typical" German snack or street food, and, if so, to find a good recipe, but I've had no luck. I know I could just make dumplings, cook cabbage and dollop some sour cream on top, but does anyone know if this is a typical German food or have a recipe? My google searches have been fruitless. Thanks.
