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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, beat the egg whites until stiff peaks form.
In another bowl, mix the egg yolks and granulated sugar until well combined.
Make the batter
Gently fold the flour, cream of tartar, and orange extract into the yolk mixture.
Carefully fold in the beaten egg whites until just combined.
Bake
Pour the batter into a cake pan and bake for 45 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.

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
- Egg whites
- Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
- Egg yolks
- Add richness and fat, adding tenderness and colour to the crumb.
- Flour
- Forms the gluten network that gives the baked cake its set structure.
- Granulated sugar
- Sweetens the batter and helps stabilise the yolks, adding tenderness to the crumb.
- Cream of tartar
- Stabilises the whipped egg whites, helping them hold their peaks.
The step that matters
Carefully fold in the beaten egg whites. Whipped egg whites hold the cake's air. Stirring or deflating them too hard releases that air, so the cake bakes up dense instead of light and airy.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
