"So wrong it's right" Potato Salad

This was my first time making my grandmother's famous potato salad, and when I read the ingredients I actually had to call Mom because the first ingredient on the list confused me so much.  It also explained why I loved this salad so much as a kid.  That's because the first ingredient is BUTTER - yes folks - a salad made with BUTTER.  According to Mom, my grandmother used to use a full cup of butter to make this recipe, but over the years Mom cut it back to 1/4 cup, and I think you could even cut this in half again to 1/8 cup. 

Anyway, that's why I'm renaming this from Peggy's Potato Salad to a more modern "So wrong its right" Potato Salad - because adding butter to any type of salad is so wrong, BUT it tastes soooo right.

Makes 5 lbs of potato salad - enough to feed an army

Ingredients
5 lbs red potatos
2 tbsp butter
1 medium Vidalia (sweet) onion, diced
2 celery stalks, sliced
1/2 green pepper, diced
4 oz jar pimientos, including juices
3/4 cup green olives, sliced
3 tsp mustard (any type will do)
1 tsp salt
1 tsp Nature's Seasoning
Several generous sprinkles of pepper and dried dill
1/2 cup mayonnaise

Boil potatoes in a large pot.  The easiest way to get evenly cooked large quantities of potatoes is to start them in cold water and once the water finally starts boiling (its going to take a while) boil them for 15 minutes.

While your potatoes are boiling, put the butter and the onions in a large bowl and microwave for 2 minutes until butter is melted and onions have started to soften.  Add all ingredients except mayo to bowl and set aside.

When potatoes are done boiling, drain water, then peel potatoes (the skin should pretty much come right off) and place them in the large bowl with other ingredients while they are still hot so they absorb the flavors.  Using two knives, cut the potatoes into large chunks and use hands to toss evenly with the other ingredients.  Allow to cool for 15 - 30 minutes on the counter, then add mayo and toss with hands to mix evenly.  Season with additional salt and pepper as needed, then chill until ready to serve.

Enjoy!
