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 ↓
Orange Jelly 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 and bake the cake
Preheat the oven to 350°F (175°C).
In a bowl, combine flour, sugar, cold water, orange juice, orange peel, egg yolks, salt, baking soda, and cream of tartar.
Mix until smooth and pour the batter into 4 jelly tins.
Bake until a toothpick inserted comes out clean.
Frost and assemble
For the frosting, beat the reserved egg white with powdered sugar until stiff.
Grate in the peel of another orange and add its juice to the frosting.
Spread the frosting between the layers of cake.

Flour and egg 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
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Sugar
- Adds sweetness and helps keep the cake tender and moist.
- Eggs
- Yolks add richness and structure, while whites help the cake rise and set.
- Baking soda
- Reacts with acidic ingredients to release gas that helps the cake rise.
- Cream of tartar
- Adds acidity that works with baking soda and stabilizes the egg whites.
- Orange
- Its juice and peel add acidity and fresh citrus aroma to the cake and frosting.
The step that matters
Beating the reserved egg white for the frosting. Egg whites only whip to stiff peaks when free of yolk and grease. Any fat left in the bowl or whites will keep them from stiffening properly.
Swap the orange
How well each one fits the dish's main ingredients (flour, sugar, egg, cream):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against flour, sugar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
