Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Gilt-edge Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, flour, water, Cottolene, baking soda, cream of tartar, and egg yolks until smooth.
Divide the batter into three layers and bake until golden.
Make the filling
For the filling, combine ¾ cup sugar with enough water to dissolve, then boil.
Add beaten egg whites to the boiling mixture and mix well.
Stir in vanilla and lemon juice.
Assemble
Spread the filling between the layers and on top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's layers together as it bakes.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
- Cottolene
- Adds fat that tenderizes the crumb and gives a soft texture.
- Baking soda
- Reacts with the acid in cream of tartar to produce gas that lifts the batter.
- Cream of tartar
- Acts as an acid that reacts with baking soda, helping the cake rise and stay light.
- Egg whites
- Whipped into the hot syrup, they add air and help the filling set light and fluffy.
The step that matters
Adding the egg whites to the boiling syrup. The whites must be beaten and added while the syrup is hot and mixed well. The hot sugar cooks the egg proteins and sets them into a light, stable filling rather than a runny or lumpy one.
