5 pounds of red potatoe
1 pound of bacon
1 large white onion (chopped)
½ cup water
1 cup cider vinegar
5 tablespoon sugar
2 ½ tablespoon koshers salt
2-3 grainy mustard
Cook potatoes in salted water on a gentle boil. When tender, drain and let cool enough to peel and slice into small disk into a large bowl.
In the meantime, cook bacon and set aside. Drain off all the fat except for about 2 tablespoons. Cook onion until translucent. Mix water, vinegar, sugar, kosher salt, grainy mustard. Add the onion in the same skillet and cook for 4-5 minutes and reduce some.
Add hot onion mixture to sliced potatoes and lightly toss. Chopped bacon and sprinkle over the top of potatoes. Let stand for about 1 hour at room temperature so the potatoes will soak up the dressing.
