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

What each ingredient does

Boiled rice
Forms the body of the croquettes, giving them bulk and a soft interior.
Egg yolks
Bind the rice mixture so the balls hold their shape.
Flour
Forms a dry coating that helps the outside brown when fried.
Lard
Conducts heat for frying, browning the outside and adding richness.

The step that matters

Frying the balls in hot lard. If the lard is not hot enough, the croquettes absorb excess fat and turn greasy instead of crisping. Hot fat sets the flour coating quickly, so the outside browns before the inside gets oily.
