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 ↓

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).
Make the batter
In a mixing bowl, combine the sugar and eggs, and beat until light and fluffy.
Gradually add the flour and baking powder, mixing well.
Stir in the water until the batter is smooth.
Pour the batter into a greased cake pan.
Bake
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

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
- Whipped with sugar to trap air, giving the cake its light, fluffy structure.
- Flour
- Forms the gluten network that sets the cake's structure as it bakes.
- Sugar
- Sweetens the cake and helps hold air in the beaten eggs for lightness.
- Baking powder
- Releases gas in the batter so the cake rises and becomes tender.
The step that matters
Beating the sugar and eggs until light and fluffy. Beating incorporates air that expands in the oven and gives the cake its lift. Underbeating leaves a dense cake, while overmixing the flour afterward can toughen it.
