Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Golden 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 bowl, cream together the sugar and butter until light and fluffy.
Add the beaten egg yolks and mix well.
Stir in the lemon zest and flour.
Add the dissolved baking soda and mix thoroughly.
Before baking, incorporate the lemon juice into the batter.
Bake and finish
Pour the batter into flat pans and bake until golden.
Ice the cake immediately after removing from the oven.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- All-purpose flour
- Forms the main structure that holds the cake together as it bakes.
- Butter
- Adds richness and a tender crumb by coating flour and trapping air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
- Egg yolks
- Add richness, moisture, and help bind the batter into a smooth emulsion.
- Baking soda
- Reacts with acid in the batter to release gas, helping the cake rise.
- Lemon juice
- Adds acidity and bright flavor, and reacts with the baking soda to aid rising.
The step that matters
Adding the lemon juice just before baking. Lemon juice is acidic and reacts with the baking soda right away, releasing gas that lifts the batter. If it sits too long before baking, much of that lift is lost, so the batter should go into the oven promptly.
