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 mixing 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.
Dissolve the sal volatile in hot water and add it to the mixture, beating well.
Finally, add the lemon juice and mix thoroughly.
Bake and finish
Pour the batter into flat pans and bake until golden.
Ice the cake immediately after baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Builds the cake's structure as its proteins set during baking.
- Granulated sugar
- Sweetens the cake and, creamed with butter, helps give a tender crumb.
- Unsalted butter
- Adds fat for richness and a tender, moist texture.
- Egg yolks
- Add richness and moisture, and help bind the batter.
- Lemon juice
- Adds acidity and bright lemon flavour.
- Sal volatile
- Acts as an optional leavening agent, releasing gas that lightens the batter.
The step that matters
Creaming the sugar and butter until light and fluffy. Beating air into the butter and sugar creates tiny bubbles that expand in the oven and lighten the crumb. If it is under-creamed, the cake will be denser.
