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 ↓
Ice-water 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
In a bowl, beat the egg yolks and sugar with 1 tablespoon of water until thoroughly combined.
In another bowl, combine the flour and baking powder.
Make and bake the batter
Gradually add the flour mixture to the yolk mixture, mixing until smooth.
Gently fold in the egg whites until well incorporated.
Pour the batter into a greased cake pan and bake for about 30-35 minutes or until a toothpick comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Forms the gluten network that gives the cake its structure.
- Eggs
- Provide structure and richness, and the whites trap air that lifts the batter.
- Sugar
- Sweetens the cake and tenderizes its crumb.
- Baking powder
- Releases gas during baking, causing the cake to rise.
- Ice water
- Adds moisture that hydrates the flour and keeps the batter loose.
The step that matters
Gently fold in the egg whites. The whites hold air that makes the cake light. Stirring vigorously or overmixing deflates them, so the cake rises less and turns 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.
