This is very simple dish to make. Pork lightly sauteed and then braised in beer and onions until tender. The sauce is thickened with sour cream and caraway seeds to make a easy quick meal. Now you can use any cut of pork you like, but personally I like pork loin medallions or loin chops. I usually buy a whole pork loin and cut my own slices to get the exact thickness I want, and it also more cost effective. Besides, I freeze the other slices for another day. Serve this with German spaetzle which is available at most grocery stores, Whole Foods and certainly local ethnic markets. The last time I made this dish I did a quick saute of cabbage, butter, salt and pepper which was perfect with this.
