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
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, beating well after each addition.
Sift the flour and gently fold it into the mixture, adding the water gradually.
Bake
Pour the batter into a greased cake tin lined with buttered paper.
Bake in a moderate oven at 350°F (175°C) for about 1 hour.
When the cake is half cooked, place the citron peel on top.

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 give a tender, rich crumb.
- Castor sugar
- Creamed with butter to aerate the batter and add sweetness and browning.
- Self-raising flour
- Provides the structure of the cake once gently folded into the batter.
- Eggs
- Add structure, richness and moisture, and help bind the batter as it sets.
- Citron peel
- Adds a bright, aromatic citrus flavour to the finished cake.
The step that matters
Folding in the flour. Folding gently keeps the air beaten into the butter and eggs. Overmixing develops gluten in the flour, which can make the cake dense and tough.
