Why it works: Cream and butter 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 ↓
Caramel Cake
Ingredients
Directions
Prepare the batter base
Add baking soda to the sour cream.
Mix baking powder with the flour.
In a bowl, combine whole eggs, sour cream, baking soda, melted butter, and half of the flour mixture. Beat for 10 minutes.
Make the sugar syrup and egg whites
In a saucepan, melt the sugar over low heat, stirring occasionally to prevent burning. Once dark brown, add 1 cup of water and boil until it threads.
Add a pinch of salt to the egg whites and beat until stiff.
Pour the melted sugar over the beaten egg whites and beat slowly until cold.
Finish the batter and bake
Add half of the sugar mixture to the batter and beat slowly for 15 minutes.
Incorporate the remaining flour mixture and beat for another 10 minutes.
Gently fold in the rest of the melted sugar.
Bake in a loaf or layer pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the starch and gluten that give the cake its structure.
- Egg whites
- Beaten into foam, they trap air that lifts the cake's crumb.
- Whole eggs
- Add richness and help bind the batter and set the structure.
- Sour cream
- Adds moisture and acidity, which reacts with baking soda to lift the batter.
- Baking powder
- A leavening agent that releases gas to make the cake rise.
- Granulated sugar
- Caramelized into the batter, it adds deep flavor, color and sweetness.
The step that matters
Pour the melted sugar over the beaten egg whites and beat slowly until cold.. The syrup must be cooled and added to the foam gently. Hot or rapidly mixed sugar can deflate the egg white foam, and the air it holds is what lifts the cake.
