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

What each ingredient does

Eggs
Bind the thickened mixture and help it set firm enough to cut and coat.
Flour
Thickens the milk mixture so it sets firm enough to cut into squares.
Corn starch
Thickens the milk mixture, giving a smooth, firm set when cooled.
Sugar
Adds sweetness and helps the croquettes brown when fried.
Butter
Adds richness and a softer, smoother texture to the filling.
Milk
Forms the liquid base that thickens into the custard.

The step that matters

Let the mixture cool fully before cutting. The starch and flour must set as the custard cools; cutting while warm causes soft, misshapen squares that fall apart when coated and fried.

Swap the walnut

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

  1. Almondfits better
  2. Walnutthe original
  3. Peanutfits about as well
  4. Beansfits about as well

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