Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rice Flour Sponge Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
In a mixing bowl, combine the rice flour and a little salt.
Make the batter
In another bowl, beat the 9 egg yolks until frothy.
Gradually add the rice flour mixture to the egg yolks, mixing well.
Bake
Pour the batter into a greased cake pan.
Bake until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice flour
- Forms the cake's crumb and body, since it contains no gluten to provide structure.
- Eggs
- Yolks add richness and help bind the batter, giving the cake its structure as it sets.
The step that matters
Gradually add the rice flour mixture to the egg yolks, mixing well.. Rice flour has no gluten, so the batter depends on the egg yolks for structure. Adding the flour gradually and mixing thoroughly prevents lumps and keeps the batter smooth and evenly bound.
