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
- Beaten whites add lift and airiness, while yolks bind and enrich the cakes.
- Flour
- Thickens the mixture so it holds its shape rather than spreading when baked.
- Rice
- Forms the body of the cakes, giving a soft, tender texture.
- Butter
- Adds fat for richness and a softer crumb.
The step that matters
Beating the egg whites separately. Whites beaten to stiff peaks trap air that expands in the oven, giving lift. Folding them in gently keeps that air from collapsing, so the cakes stay light rather than dense.
“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.
