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.
Prepare
Boil the sugar with ½ cup of water to make a syrup.
Prepare a cake tin as for sponge cake.
Make the batter
In a bowl, beat the eggs with the syrup for 20 minutes.
Add the melted butter and mix in the flour lightly with the grated lemon rind.
Bake
Bake the cake for about 1 hour in a moderate oven 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
- Eggs
- Beaten with the syrup to trap air, giving the cake its light, structured crumb.
- Butter
- Melted into the batter to add richness, fat and a tender texture.
- Vienna flour
- Mixed in lightly to form the cake's structure as the batter sets during baking.
- Loaf sugar
- Boiled into a syrup to sweeten the cake and help give it a fine, moist crumb.
The step that matters
Beating the eggs with the syrup. Beating for a full 20 minutes traps air in the eggs, which is what lifts the cake. Under-beaten batter bakes dense and heavy.
