Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potato
- Forms the bulk of the stuffing and gives it a soft, moist body.
- Egg yolks
- Enrich the mixture and help bind it as it sets with heat.
- Butter
- Adds fat for richness and a smoother, moister texture.
- Cream
- Adds moisture and richness, softening the mixture.
The step that matters
Add the cream to the beaten egg yolks and mix them with the potato. Egg yolks can scramble or cook unevenly if they meet hot potato directly. Combining them with cream first dilutes and cools them, so they blend smoothly into the mash.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, butter, egg, cream, parsley):
- Chivefits better

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