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
