Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Peach Cakes
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the yolks and whites of the eggs separately, whipping the whites to stiff peaks.
Mix the beaten yolks with the powdered sugar and beat together for 15 minutes.
Gradually add the flour, mixing well.
Fold in the egg whites for 4-5 minutes.
Bake and assemble
Preheat the oven to 400°F (200°C).
Drop spoonfuls of batter onto a buttered and floured baking sheet, shaping them like half peaches.
Bake the cakes for about 10 minutes until lightly browned.
Spread the flat side of each cake with peach jam.
Sandwich the cakes in pairs.
Cover the outside with a thin layer of icing.
Brush one side with cochineal water once dry.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air to lighten the batter, while yolks add richness and structure.
- Powdered sugar
- Sweetens the batter and, beaten with the yolks, helps create a light, fine texture.
- All-purpose flour
- Provides the starch that sets the batter into a sturdy cake structure as it bakes.
- Peach jam
- Adds fruity sweetness and moisture between the cake halves.
The step that matters
Folding in the egg whites. Whipped whites are full of trapped air, and over-mixing or stirring them vigorously deflates the foam, leading to flat, dense cakes. Fold gently, just until no white streaks remain.
Swap the peach
How well each one fits the dish's main ingredients (egg, sugar, flour):

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