Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the butter and sugar until light and fluffy.
Stir in the cream.
Gradually mix in ¼ of the flour.
Whisk the eggs until thick.
Add them gradually to the mixture.
Add the remaining flour in two parts, alternating with the lemon juice and zest.
Mix in the baking soda.
Beat for a few more minutes.
Line pans and bake
Line your pans with parchment paper.
Bake in a moderate oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and adds richness and a tender crumb.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light, tender texture.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Add structure, moisture and richness, helping the batter set as it bakes.
- Cream
- Adds moisture and richness, giving a softer, more tender crumb.
- Baking soda
- Reacts with the acidic lemon juice to produce gas that helps the cake rise.
The step that matters
Add the eggs gradually to the mixture. Adding eggs slowly lets each addition emulsify into the butter and sugar. Adding them all at once can cause the batter to curdle or separate, which affects the final texture.
