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
- Eggs
- Bind the mixture and add structure and richness as they set during baking.
- Flour
- Thickens the mixture so it holds its shape rather than spreading.
- Butter
- Adds fat for richer flavor and a tender texture.
- Cooked rice
- Forms the body of the cakes, providing bulk and a soft, tender crumb.
The step that matters
Beat the egg whites and yolks separately, then mix them into the rice.. Beaten egg whites trap air that helps the cakes rise and lighten, while the yolks add richness. Folding them in gently keeps that air from being lost before baking.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
