Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Peach 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).
Beat the eggs hard for five minutes.
Add the sugar and beat for three minutes.
Mix in the cold water, flour, and baking powder.
Pour the batter into two deep round cake tins and bake until golden.
Assemble and serve
Once cooled, split each cake in half and spread with cut‑up peaches.
Sprinkle with fine sugar and cover with whipped cream.
Top with the second cake layer, sprinkle with powdered sugar, and serve as a dessert.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped by hand, they trap air that gives the cake its light structure.
- Flour
- Its proteins set during baking to form the cake's main structure.
- Baking powder
- Releases gas when heated, helping the batter rise.
- Sugar
- Sweetens the cake and helps keep it tender and golden as it bakes.
- Peaches
- Add moisture, fruity sweetness and acidity between the cake layers.
- Whipped cream
- Adds richness and moisture to the filling.
The step that matters
Beating the eggs. Beating the eggs hard incorporates air that the batter depends on for lift. Under-beating leaves a dense cake, while the batter should be baked soon after mixing so the trapped air and baking powder's gas are not lost.
Swap the peach
How well each one fits the dish's main ingredients (egg, sugar, flour, cream):

- Peachthe original
Fit is the average pairing score against egg, sugar, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
