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 says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
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 them in with the lemon rind.
Bake
Place the mixture in a well-buttered cake tin.
Bake for 45 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and a tender crumb.
- Eggs
- Add structure and moisture, binding the batter as the cake sets.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the oven so the cake rises and becomes light.
- Castor sugar
- Sweetens the cake and helps hold air in the creamed butter mixture.
The step that matters
Adding the eggs one by one. Adding eggs slowly and beating well after each one keeps the emulsion stable. If they go in too fast, the batter can curdle and trap less air, leading to a denser cake.
