Why it works: Vanilla and milk are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Burnt Sugar 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 burnt sugar
To make burnt sugar, place 1 cup sugar in a heavy pan and cook until it smokes, stirring constantly.
Add 1 cup water to the burnt sugar and cook until a thin syrup forms.
Mix and bake
In a bowl, cream the butter and sugar together.
Add the eggs, milk, and burnt sugar syrup to the mixture and mix well.
Sift the flour and baking powder together, then gradually add to the wet ingredients.
Pour the batter into a greased cake pan.
Bake in a moderate oven at 350°F (175°C) 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
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Provide structure as they set and add moisture and richness to the batter.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Burnt sugar
- Adds a deep, bittersweet caramel flavour and colour to the cake.
The step that matters
Cooking the burnt sugar. Sugar must be taken to smoking without being allowed to turn fully black and bitter. Stirring constantly prevents hot spots that burn unevenly, so the flavour stays deep rather than acrid.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, milk, sugar, flour, egg):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, milk, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
