Potato Salad

I am pretty picky about potato salads, I usually think it sounds good and then I am almost always dissapointed.

My roommate made this recipe today and I was pleasently surprised so I thought I better mark it down.  It is a bit sweeter than traditional potato salad, but had a nice variety of flavors.  I also believe that you can toss in whatever you want to salads so I will just give the dressing recipe.

7 potatoes cooked, peeled, and cubed

Dressing: 

1/2 cup sugar
1 Tbsp cornstarch
1/4 cup vinegar
1/2 cup milk
1 egg
4 Tbsp butter
1 tsp celery seed
1/2 tsp dry mustard
1 tsp salt
1/4 cup mayo
1/4 cup onion, chopped

Combine sugar and cornstartch in a saucepan. Add vinegar, milk, egg, butter, celery seed, salt, and dry mustard.  Cook over a low heat, stirring continually until thick and bubbly.  Stir in the mayo and chopped onion.  Cool.  Gently fold sauce over potatoes.  Add additional stuff and refridgerate until ready to serve.

3-5 hard boiled eggs, chopped
small cubes of cheddar cheese
salt, pepper, paprika
a little bit of mustard to taste
chopped celery
1/2 cup dill pickle relish or chopped pickles
