Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Well-boiled rice
- Forms the bulk of the croquette and gives a soft, tender interior.
- Beaten eggs
- Bind the rice together so the balls hold their shape while frying.
- Melted butter
- Adds fat and richness, contributing to a tender interior.
- Sugar
- Adds sweetness and helps the exterior brown during frying.
- Flour
- Forms a dry coating that helps the outside crisp and brown in the hot fat.
- Boiling lard
- Heat transfer medium that fries the outside to a golden, crisp crust.
The step that matters
Drop the coated rice balls into the boiling lard and fry until golden brown.. If the lard is not hot enough, the coating absorbs fat and turns greasy and the centre stays cold. A deep pan of properly hot fat seals the flour coating quickly, so the outside browns before the interior overcooks or falls apart.
