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

What each ingredient does

Potatoes
Provide starch and body, giving the rolls a soft, moist crumb.
Egg yolks
Add richness and tenderness, and help bind the dough.
Butter
Adds fat for softness and a richer flavor in the crumb.
Milk
Adds moisture and some sweetness and browning from milk sugars.
Yeast
Produces gas that makes the dough rise and become airy.
Flour
Provides gluten and structure so the stiff dough holds its shape.

The step that matters

Gradually add flour until a stiff dough forms. Adding flour in stages lets you stop once the dough is stiff but still soft. Too much flour makes the rolls dense and dry, while too little leaves a sticky dough that is hard to shape.

Swap the potato

How well each one fits the dish's main ingredients (butter, egg, milk, flour):

  1. Chivefits about as well
  2. Potatothe original
  3. Leekfits about as well
  4. Asparagusfits about as well

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