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 ↓
Madeira Cake
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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Sift the flour and cream the butter and sugar together.
Add the grated lemon rind.
Gradually add the flour and eggs, beating well after each addition.
Mix in the baking powder with the last spoonful of flour.
Bake and serve
Pour the batter into a greased tin and place the citron on top.
Bake in the preheated oven for 1.5 hours until golden.
Let cool before serving.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake's crumb together as it bakes.
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich texture.
- Castor sugar
- Creamed with butter to add sweetness and help create a light, aerated batter.
- Eggs
- Add structure, richness and moisture, and help bind the batter.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Gradually add the flour and eggs, beating well after each addition. Adding eggs slowly and beating between additions keeps the batter stable. If it curdles, the emulsion breaks and the cake can turn out dense or greasy.
