Why it works: Butter and flour 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 ↓
Madeira 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.
Make the batter
Cream the butter and sugar together with a wooden spoon.
Add the eggs one by one, beating them well after each addition.
Sift the flour and baking powder together, then lightly stir in the lemon rind.
Bake
Pour the mixture into a well-buttered cake tin.
Bake at 350°F (175°C) for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a tender crumb, and creaming it traps air for lift.
- Sugar
- Sweetens the cake, helps browning, and creams with butter to aerate the batter.
- Eggs
- Bind the batter, add structure, and emulsify the fat for a smooth mix.
- Flour
- Forms the structure that holds the cake's shape as it bakes.
- Baking powder
- Releases gas in the oven, helping the cake rise and become light.
- Lemon rind
- Contributes bright citrus aroma without adding much liquid.
The step that matters
Adding the eggs one at a time. Eggs added gradually and beaten in fully stay emulsified with the butter. Adding them all at once or too fast can curdle the batter, which may give a dense, heavy cake.
