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

What each ingredient does

Eggs
Bind the dough and add richness and structure as they set in the oven.
Butter
Adds fat for a tender crumb and rich flavor.
Mashed potatoes
Add moisture and softness, helping the rusks stay tender.
Yeast
Ferments the dough so it rises and becomes light and airy.
Flour
Provides the structure that holds the dough together as it rises and bakes.

The step that matters

Add flour until the dough is workable. Too much flour makes the rusks dense and dry, while too little leaves a sticky dough that is hard to shape and may not hold its rise well.

Swap the potato

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

  1. Sweet potatofits better
  2. Arrowrootfits better
  3. Chivefits about as well
  4. Potatothe original

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