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 ↓
Balmoral Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Break the eggs into a bowl and add the sugar.
Sift the flour.
Make the batter
Beat the eggs and sugar together for 20 minutes over a bowl of hot water.
When thick and creamy, quickly stir in the flour.
Bake and cool
Grease a cake tin and sprinkle with sugar.
Pour in the mixture and bake at 300°F (150°C) for 20 to 30 minutes.
Turn out onto a wire rack to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked into a foam that traps air, and their proteins set to form the cake's structure.
- Sugar
- Sweetens the cake and helps stabilise the whisked egg foam so it holds its volume.
- Flour
- Its starch and gluten set as the cake bakes, giving the sponge its firm structure.
The step that matters
Quickly stir in the flour. Folding in the flour gently and briefly keeps the whisked egg foam from deflating. Overmixing knocks out the trapped air and develops gluten, which makes the cake dense and tough.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
