What is the difference between Russian salad dressing and Thousand Island dressing?

There is no "Russian Salad Dressing". You might be thinking of Russian Salad, a cold potato salad commonly made with peas, carrots, pickles, and mayonnaise.

Thousand Island Dressing is a creamy, tangy dressing that is often served with seafood and salads. It's generally made with mayonnaise, ketchup, chopped sweet pickles, and sometimes other ingredients like hard-boiled eggs, paprika, onion, garlic, or Worcestershire sauce.

Here's a breakdown of the differences:

Russian Salad:

* A dish, not a dressing: It's a cold potato salad with various vegetables.

* Main ingredients: Potatoes, peas, carrots, pickles, mayonnaise.

* Flavor: Creamy and savory, often with a tang from the pickles.

Thousand Island Dressing:

* A dressing, not a dish: It's a creamy, tangy dressing.

* Main ingredients: Mayonnaise, ketchup, chopped sweet pickles.

* Flavor: Creamy, tangy, and slightly sweet.

Therefore, while both are related to mayonnaise and often enjoyed with salads, they are distinct dishes with different ingredients and flavor profiles.
