Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
French 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, beat the eggs and sugar together until light.
Add the sweet milk and melted butter, mixing well.
Sift the flour and baking powder together, then gradually add to the mixture.
Stir in the lemon extract.
Bake
Pour the batter into a greased cake pan.
Bake for 30-35 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set during baking.
- Sugar
- Sweetens the cake and helps it brown while beating in air.
- Sweet milk
- Adds moisture and hydrates the flour to form the batter.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Flour
- Forms the main structure of the cake as its proteins set.
- Royal baking powder
- Releases gas when heated, helping the cake rise.
The step that matters
Sift the flour and baking powder, then add gradually. Evenly distributing the baking powder prevents pockets of leavening that cause uneven rising or bitter spots. Adding flour gradually keeps the batter smooth and avoids overmixing, which toughens the crumb.
Swap the lemon
