Creamy Potato Salad

My friend brought this potato salad to a BBQ recently, and it was the best potato salad I had ever tasted!  I LOVED it!  Of course, I begged for the recipe and used this same salad for our 4th of July festivities - it was a hit!
 

She found the recipe on online at all recipes, but altered it a bit to suit her tastes.  I made it exactly like my friend did.  www.allrecipes.com says: "This is the creamiest, richest potato salad you will ever try. The secret is in the homemade dressing. I get nothing but raves every time I make this."

Ingredients:

• 6 medium potatoes 
• 1 bunch of green onions, finely chopped 
• 1 teaspoon salt 
• 6 hard-cooked eggs, diced 
• 2 eggs, beaten 
• 1/2 cup white sugar 
• 1 teaspoon cornstarch 
• salt to taste 
• 1/2 cup vinegar 
• 1 (5 ounce) can evaporated milk 
• 1 teaspoon prepared yellow mustard 
• 1/4 cup butter 
• 1 cup mayonnaise 
• 6-10 pieces of bacon, cooked and crumbled (optional, but a must in my house ;)

Directions:

1. Place the potatoes into a large pot, and fill with enough water to cover. Bring to a boil, and cook for about 20 minutes, or until easily pierced with a fork. Drain. Cool, peel and dice. Transfer to a large bowl, and toss with the onion, 1 teaspoon of salt, and hard-cooked eggs.

2. While the potatoes are cooking, whisk together 2 eggs, sugar, cornstarch, and salt in a saucepan. Stir in the vinegar, milk, and mustard. Cook over medium heat, stirring frequently, until thickened, about 10 minutes. Remove from heat, and stir in the butter. Refrigerate until cool, then stir in the mayonnaise.

3. Stir the dressing and the cooked and crumbled bacon into the bowl of potato salad gently until evenly coated. Chill several hours or OVERNIGHT before serving for best flavor.
