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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a clean bowl, combine the butter and sugar, then add the grated lemon rind.
Using your hands, cream the mixture until very light.
Add the eggs one at a time, beating well after each addition.
Once all eggs are added and the batter is light and creamy, gently fold in the flour.
Bake
Divide the mixture equally into 3 or 4 round cake tins lined with buttered parchment paper.
Dust sugar over the top and place 2 thin slices of citron peel on each cake.
Bake in a moderate oven at 350°F (175°C) for 1 to 1.5 hours.

Butter and flour 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
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- All-purpose flour
- Provides the structure that sets the cake as the batter bakes.
- Caster sugar
- Creams with the butter to aerate the batter and adds sweetness and gentle browning.
- Eggs
- Add structure and richness, and their proteins set during baking to hold the crumb together.
The step that matters
Folding in the flour. Once the flour is added, overmixing develops gluten and makes the cake tough and dense. Fold gently, just until the flour disappears, so the air trapped in the creamed batter is preserved.
