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

What each ingredient does

Flour
Starch that thickens the water and butter into a paste that holds its shape.
Egg yolks
Add richness and fat, and help the dough emulsify and stay tender.
Egg whites
Trap steam as the dough fries, helping the puffs expand and turn light.
Butter
Adds fat and flavor and keeps the dough tender.

The step that matters

Drop spoonfuls into boiling clarified dripping or lard to fry until golden brown.. The fat must be hot enough to set the outside quickly. If it is too cool, the dough absorbs grease and turns heavy instead of puffing.

Swap the ginger

The recipe marks ginger as optional. How well each one fits the dish's main ingredients (butter, flour, egg):

  1. Capersfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. Gingerthe original

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