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):
- Arrowrootfits better
