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 Cake
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make and bake the batter
In a large bowl, beat the eggs and gradually add the sugar, flour, baking powder, grated orange rind, and orange juice. Mix until well combined.
Turn the batter into well-buttered shallow tins.
Bake in the preheated oven until golden brown.
Assemble and finish
Once baked, make a sandwich cake by placing a layer of orange marmalade between the two layers.
Sprinkle sifted sugar on top.

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
- Eggs
- Beaten to trap air, giving the cake its light structure as it sets in the oven.
- All-purpose flour
- Provides the main structure that sets the batter as it bakes.
- Sugar
- Sweetens the cake and helps it brown to a golden colour in the oven.
- Sour cream
- Adds moisture and tenderness to the crumb, along with a slight tang.
- Baking powder
- Releases gas during baking so the cake rises and becomes airy.
- Orange marmalade
- Adds bright citrus flavour and sweetness to the filling between the layers.
The step that matters
Beating the eggs before adding the other ingredients. Beaten eggs hold air bubbles that lift the batter. If they are under-beaten or deflated by overmixing, the cake may bake up dense and flat.
Swap the orange
How well each one fits the dish's main ingredients (sugar, flour, cream, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, flour, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
