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 ↓
Sunshine Cake
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 the batter
Preheat the oven to 300°F (150°C).
Beat the egg whites until stiff peaks form.
Gradually add the sugar to the beaten egg whites.
Beat the egg yolks.
Combine the beaten egg yolks with the beaten egg whites and orange extract.
Fold in the flour until just combined.
Bake
Pour the batter into pans.
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 into stiff peaks to trap air, giving the cake its light, airy structure.
- Egg yolks
- Add richness and fat, softening the crumb and contributing to color and flavor.
- Granulated sugar
- Stabilizes the whipped whites and adds sweetness and tenderness to the crumb.
- All-purpose flour
- Provides gentle structure that sets the cake once folded into the batter.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a more stable, voluminous foam.
The step that matters
Fold in the flour until just combined. Overmixing after the flour is added develops gluten and deflates the whipped egg whites, producing a dense, tough cake instead of a light one.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, flour, cream):
- Raisinfits better
- Vanillafits better
- Figfits better
- 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.
