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 ↓
Burnt Sugar Cake
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°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 salt, egg yolks, and cold water, mixing well.
In a separate pan, burn ½ cup sugar until smoking brown, then carefully add ½ cup hot water to make caramel.
Combine the caramel with the batter.
Sift the flour and baking powder together, then fold into the batter.
Bake and frost
Bake in layers at 400°F (200°C) for about 20 minutes.
For the frosting, burn 4 tablespoons of sugar and add it to boiled frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender, rich texture.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Egg yolks
- Add richness and help bind the batter while adding moisture.
- Sugar
- Sweetens the cake and, when burned, adds a deep bitter-caramel flavour and colour.
The step that matters
Burning the sugar for the caramel. Sugar must be taken to smoking brown to develop a deep caramel flavour, but if it burns past that point it turns bitter. Adding the hot water carefully is needed because the caramel can spatter and seize.
