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 ↓
Rice Croquette

Directions
Make the mixture
In a bowl, cream together the melted butter and sugar.
Add the cold boiled rice and salt, then stir in the beaten eggs to form a smooth paste.
Shape and coat

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled rice
- Forms the bulk of the croquette and gives it a soft, starchy body.
- Eggs
- Bind the rice into a smooth paste that holds its shape while cooking.
- Butter
- Adds richness and a tender mouthfeel to the mixture.
- Sugar
- Adds gentle sweetness and helps the exterior brown during frying.
- Cracker flour
- Forms a dry crust that crisps and browns in the hot lard.
The step that matters
Fry in hot lard until golden brown. If the lard is not hot enough, the coating absorbs fat and turns greasy before it crisps, while the interior may stay cool. Hot fat sets the crust quickly and browns it.
