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 ↓
A Good Madeira Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Whisk the eggs until light.
Gradually add the sugar while whisking.
Add the flour, then the melted butter, and the lemon rind.
Before molding the cake, mix in the baking soda.
Bake
Bake in a moderate oven (350°F / 175°C) for 1 hour.

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
- Eggs
- Whisked eggs trap air and add structure as the cake sets.
- Powdered sugar
- Sweetens the cake and adds tenderness to the crumb.
- All-purpose flour
- Provides the main structure once the batter bakes and sets.
- Unsalted butter
- Adds richness, moisture and fat for a tender texture.
- Baking soda
- Reacts to lift the batter and help it rise in the oven.
The step that matters
Adding the baking soda before molding. Baking soda starts reacting once mixed into the batter, so it should be stirred in just before molding and baked promptly. Waiting too long lets the rise weaken and can leave the cake dense.
