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 the batter
Preheat the oven to 350°F (175°C).
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 sifted flour.
Dissolve the baking soda in a little hot water and add it to the mixture.
Beat the batter thoroughly.
Finish and bake
Just before pouring into the pan, add the lemon juice and mix well.
Pour into a greased cake pan and bake until golden.

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
- Eggs (yolks)
- Add richness and structure, helping the batter set firmly as it bakes.
- Butter
- Creams with the sugar to trap air, giving a tender, rich crumb.
- All-purpose flour
- Forms the cake's structure once its proteins set in the oven.
- Granulated sugar
- Sweetens the cake and helps create a light, aerated batter when creamed.
- Baking soda
- Reacts with the acidity in the lemon to produce gas that lifts the cake.
- Lemon juice
- Adds acidity and bright flavour, and reacts with the baking soda to help rising.
The step that matters
Adding the lemon juice just before baking. Lemon juice reacts with baking soda to release gas. If it sits too long before baking, much of that lift is lost, so the cake may bake up flat and dense.
