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 Flour Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat oven to 350°F (175°C).
Beat egg yolks and whites separately until fluffy.
Make the batter
In a large bowl, cream butter and sugar together.
Gradually add beaten egg yolks to the butter mixture.
Fold in rice flour and mix well.
Gently incorporate beaten egg whites until combined.
Add flavoring to taste.
Bake
Pour batter into greased cake pan and bake for about 30‑40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and structure, while whipped whites lighten the batter and help it rise.
- Butter
- Creamed with sugar, it traps air and adds fat for a tender, moist crumb.
- Sugar
- Creamed with butter, it adds sweetness and helps create a light, aerated texture.
- Rice flour
- Provides the main structure of the cake; being gluten-free, it gives a finer, more delicate crumb.
The step that matters
Gently incorporate beaten egg whites. Whipped whites hold the air that lightens the cake. Folding gently keeps that air in; vigorous stirring deflates the batter and yields a dense cake.
