Okay I got permission to post this one from my Mom, because I think she makes the best potato salad in the world.
8-10 Potatoes (either russet, yukon gold, or red)
1/2 cup mayo (or equivalent if you use something else)
2 1/2 TBS yellow mustard
2 TBS white vinegar
2 Hardboiled eggs, cut up
Sweet Pickles or relish (how much depends on your taste, I usually do about 2 1/2 spoonfuls)
2 tsp sweet pickle juice
Pepper (to taste)
Optional: diced celery, olives, bacon bits, bell peppers
Boil 8-10 potatoes with peels on them til you can poke them through with a fork and they are soft
Peel and cut into chunks and put into a large bowl
Add mayo, mustard, vinegar, and eggs
Take a potato masher and mash slightly, then stir together
Add sweet pickles and juice and pepper and stir again.
Add your optional ingredients and mix through
Let sit in fridge for 2 hours to chill. Overnight is best and serve. Usually I can use this for 2 meals for our family.
