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

What each ingredient does

Mashed potato
Provides the bulk and soft, moist body of the puff balls.
Egg
Binds the mixture and helps the puffs hold their shape while frying.
Flour
Adds structure so the batter holds together in the hot fat.
Baking powder
Releases gas when heated, helping the balls puff and turn light inside.
Milk
Loosens the mixture so it drops easily and stays moist.

The step that matters

Frying in deep fat. The fat must be hot enough to brown the outside quickly. If it is too cool, the balls absorb oil, turn greasy, and may not puff properly before the centers set.

Swap the potato

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

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

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