Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Gilt-edge Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the cake
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, flour, water, butter, 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 1/2 cup sugar with enough water to dissolve it and bring to a boil.
Remove from heat and stir in the beaten egg whites, mixing well.
Add vanilla and lemon extracts to the filling.
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
- Egg yolks
- Add richness and help bind the batter into a smooth, set crumb.
- Cream of tartar
- Acidifies the batter and stabilizes the leavening for a lighter texture.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Flour
- Provides the structure that holds the cake layers together.
- Sugar
- Sweetens the cake and helps it brown during baking.
- Egg whites
- Whipped into the hot syrup, they form a light, airy, marshmallow-like filling.
The step that matters
Stirring the beaten egg whites into the hot syrup. The syrup must be hot enough to cook the egg whites as they are stirred in, otherwise they stay loose and the filling does not set or hold its airy texture. Mix steadily so the whites cook evenly without scrambling.
