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 ↓
Velvet 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).
Make the batter
In a large bowl, beat the sugar and eggs together until well combined.
Gradually add the boiling water to the mixture, stirring continuously.
Sift in the flour and baking powder, mixing until smooth.
Bake
Pour the batter into prepared cake pans and bake until golden.

Flour and egg 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
- Provide structure and lift through the foam they hold when beaten with sugar.
- Flour
- Forms the structure that sets around the air and steam as the cake bakes.
- Sugar
- Sweetens the cake and helps create a fine, tender crumb when beaten with eggs.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Adding the boiling water. Pour it in gradually while stirring. Adding it all at once can deflate the egg foam and cause an uneven batter. Hot water also helps the starch gelatinize, which softens the crumb.
“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.
