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 dish, mashing into a soft, fluffy base.
Cream cheese
Adds richness and a creamy, smooth texture to the mash.
French onion dip
Supplies onion flavor and extra creaminess throughout the potatoes.
Butter
Adds fat for richer flavor and a smoother, silkier mouthfeel.
Milk
Adds moisture so the mashed potatoes become smooth and spreadable.

The step that matters

Chill for the full 8 hours or overnight. Resting cold lets the starch set and the flavors blend, so the dish holds its shape and tastes evenly seasoned once baked.

Swap the onion

How well each one fits the dish's main ingredients (potato, butter, milk, pepper, cream cheese):

  1. Chivefits better
  2. Capsicumfits better
  3. Tomatofits about as well
  4. Onionthe original

Fit is the average pairing score against potato, butter, milk, pepper, cream cheese. Candidates are from the same food group and used in at least 100 recipes.
