Potato Salad

This recipe is a 30 year old favorite. It was in a little yellow cookbook that came with my first Presto pressure cooker. I still have my beloved cooker and I still make this potato salad a few times a year. It is good hot, cold, and luke-warm. Double the recipe - you'll want leftovers. This is always a hit at summer picnics too.

4 tablespoons olive oil
2 tablespoons sugar
1 tablespoon salt
1/4 teaspoon pepper
1 teaspoon prepared mustard
1/2 teaspoon celery seed (optional)
1/4 cup vinegar (I like red wine vinegar)
1/2 cup water
1 large onion, chopped
6 large potatoes diced (red potatoes or Yukon gold are my favorites)
Add a few ribs of chopped celery and raisins if you have them handy.

Add ingredients to cooker, mix well, close cover and cook 5 minutes with pressure regulator rocking gently. Cool cooker at once. If you don't have a pressure cooker I'm sure you can bake this in a Dutch oven or cook it on the stove top in a heavy lidded pot. Save the leftover flavorful seasoned potato stock for adding to cooked beans or using as soup stock.
