I got this recipe from Elly Says Opa. These were great! I think they could have used a little more vinegar though.
Serves 4 Marth Stewart
1 lb. potatoes, cut into 1/4″ slices 2 cups white vinegar (or enough to cover potatoes) 2 Tbsp. extra virgin olive oil coarse salt and pepper
Make sure vinegar covers potatoes in a medium saucepan, and then bring to a boil. Reduce heat and simmer until just fork tender, about 5 minutes. Let potatoes cool in the vinegar for 30 minutes. Drain well.
Preheat the broiler. Toss the potatoes with oil, salt and pepper. and place in one layer on a broiler-safe pan. Broil until crispy and browned on top, just a few minutes, rotating the pan if necessary. Sprinkle with additional coarse salt before serving.
