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 Layer 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.
Make the batter
Preheat the oven to 350°F (175°C).
Beat 9 egg yolks with powdered sugar until light.
Whip the egg whites to a stiff froth. Gently fold the whipped egg whites into the yolk mixture.
Add flour, lemon juice, and baking powder. Mix the batter lightly without beating.
Divide the batter into layers.
Bake and assemble
Bake the layers until golden.
Layer the baked cakes with sweetened chopped peaches.
Beat 3 egg whites. Gradually add 3 tablespoons of sugar until stiff peaks form.
Spread the meringue on top of the cake. Bake the cake for a few minutes until browned.
Serve
Serve with cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and whipped whites lighten it, giving the cake its structure and airy texture.
- Flour
- Provides the starch and gluten that set the layers and give the cake its body.
- Powdered sugar
- Sweetens the batter and helps the yolks whip to a light, pale mixture.
- Baking powder
- Releases gas in the batter to help the layers rise.
- Peaches
- Add moisture and fruity sweetness between the layers.
- Lemon juice
- Adds acidity that brightens the flavor of the sweet batter and peaches.
The step that matters
Folding the whipped egg whites into the yolk mixture. Folding gently keeps the air in the whites; stirring or beating deflates them, leaving the layers dense instead of light.
Swap the peach
How well each one fits the dish's main ingredients (egg, flour, sugar, lemon, cream):
