Potato Salad

Ingredients

Directions

Prepare the salad

  1. Combine the sliced potatoes, sliced eggs, diced ham, sweet pickle, salt, and pepper in a large bowl. Mix thoroughly.

Make the dressing

  1. In a separate bowl, mix the salad sauce, raw egg yolks, cooked egg yolk, Worcestershire sauce, sugar, and pepper to prepare the dressing.

  2. Slowly stir in the sweet oil, similar to making mayonnaise.

  3. Add a few drops of lemon juice to the dressing.

Combine and garnish

  1. Pour the dressing over the potato mixture, one spoonful at a time, mixing well after each addition.

  2. Garnish with additional sliced eggs and pickles as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Form the bulk of the salad and absorb the dressing, giving body to each bite.
Raw egg yolks
Emulsify the oil into the dressing, thickening it into a creamy, mayonnaise-like sauce.
Sweet oil
Provides fat and richness, forming the body of the emulsified dressing.
Hard boiled eggs
Add firm texture and richness to the salad.
Potted ham
Adds savory, meaty flavor and fat to the salad.

The step that matters

Adding the oil to the dressing. Oil must be added slowly while stirring so it emulsifies into the egg yolks; adding it too fast can break the dressing into separated oil and liquid.

Swap the potato

How well each one fits the dish's main ingredients (egg, ham, pepper, sauce, sugar, lemon):
