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

What each ingredient does

Potatoes
Provide the starchy base that mashes into the dish's body.
Cream
Adds moisture and richness, making the mash smooth and soft.
Butter
Adds fat for flavour and a silkier, softer texture.

The step that matters

Mash the potatoes until very fine. Lumps remain if the potatoes are not mashed thoroughly after draining. Pushing them through fully before adding cream gives a smooth texture. Overworking cooked potatoes can make them gluey, so mash just until fine and stop.

Swap the walnut

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

  1. Almondfits better
  2. Peanutfits better
  3. Beansfits about as well
  4. Walnutthe original

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