Sunshine Cake

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 ↓

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make the batter

  1. Beat the egg whites until stiff peaks form, then gradually add the sugar while continuing to beat.

  2. In a separate bowl, beat the egg yolks and add them to the beaten whites along with the orange extract.

  3. Gently fold in the sifted flour until just combined.

Bake

  1. Pour the batter into cake pans and bake for 50 minutes.

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

Egg whites
Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
Egg yolks
Add richness, moisture and tenderness to the crumb.
Granulated sugar
Sweetens the cake and stabilizes the whipped whites, helping them hold their shape.
Flour
Provides the gentle structure that sets the cake as it bakes.
Cream of tartar
Stabilizes the whipped egg whites so they hold their volume.

The step that matters

Gently fold in the sifted flour. Overmixing knocks air out of the whipped whites, so the flour should be folded in just until combined to keep the cake light and tall.

Swap the orange

How well each one fits the dish's main ingredients (egg, sugar, flour, cream):

  3. Figfits better
  4. Orangethe 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.
