Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Rice Sponge Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a mixing bowl, beat together the sugar and eggs for 20 minutes.
Gradually add the rice flour and flavoring, mixing until well combined.
Pour the batter into a greased cake pan.
Bake
Bake for 30 minutes or until a toothpick inserted in the center comes out clean.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Whipped with sugar to trap air, giving the cake its light, airy structure.
- Rice flour
- Provides the cake's structure once baked, setting as the batter heats.
- White sugar
- Sweetens the cake and helps stabilize the whipped egg foam.
The step that matters
Beating the sugar and eggs. Beating for the full time builds a stable foam of trapped air, which is what lifts the cake. If the foam collapses when the flour is folded in, the cake will bake up dense and flat.
“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.
