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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the butter until creamy.
Add the sugar, flour, baking powder, and Katifia essence, mixing well.
In a separate bowl, beat the egg yolks and whites until well combined, then fold into the mixture.
Pour the batter into a well‑buttered cake tin.
Bake
Place two large slices of candied peel on top.
Bake for 1 hour or until a toothpick inserted comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness, and lift the batter as they are beaten and folded in.
- Butter
- Adds fat and tenderness, and carries flavour through the crumb.
- All-purpose flour
- Forms the cake's structure once it sets in the oven.
- White sugar
- Adds sweetness and helps the crumb brown and stay tender.
- Baking powder
- Releases gas in the oven, helping the cake rise and open up.
The step that matters
Folding in the egg whites. Folding gently keeps the air beaten into the mixture. Stirring hard knocks out that air, which leads to a dense, flat cake.
