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.
Make the batter
Break the eggs into a bowl and add the sugar.
Place the bowl over a saucepan of hot water and beat the mixture for 20 minutes until thick and creamy.
Sift in the flour and gently fold it into the egg mixture.
Bake and cool
Grease a cake tin and sprinkle it with sugar.
Pour the batter into the prepared tin and bake at 300°F (150°C) for 20 to 30 minutes.
Turn the cake 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 with sugar to trap air, giving the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps the egg foam hold its volume while beating.
- Flour
- Provides the starch that sets during baking to form the cake's final structure.
The step that matters
Folding in the flour. Folding gently keeps the air trapped in the whisked egg mixture. Stirring vigorously knocks out that air, leaving a denser, flatter cake.
“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.
