This dish is simply amazing. I decided not to keep the potatoes overnight in the refrigerator. Instead I put them in the freezer for 30 minutes and they came out just fine. I didnt have any bacon fat available so I used the olive oil as suggested. I thought I would miss the richness from the bacon fat, but olive oil was just fine and didnt take away from the flavor whatsoever. I like my potatoes a bit tangy so I added more malt vinegar. Yum! I highly recommend this dish for your Oktoberfest celebration!
