Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Orange Caice
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 bowl, mix sugar, flour, baking powder, and grated orange rind.
In another bowl, beat the eggs and add cold water and orange juice.
Combine the wet and dry ingredients until smooth.
Bake and ice
Divide the batter into three layers and bake until golden.
For icing, beat the egg white with water, then gradually stir in confectioner's sugar until thick.
Spread icing between layers and on top of the cake, garnishing with thin orange slices.

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
- Provide structure and richness as they set during baking, lifting the batter.
- Flour
- Forms the main structure of the cake as its proteins set when heated.
- Sugar
- Sweetens the cake and helps it brown and stay tender.
- Baking powder
- Releases gas when heated, helping the cake rise and become light.
- Orange juice
- Adds moisture and acidity, brightening the flavour of the cake.
- Confectioner's sugar
- Dissolves into the egg white to thicken the icing into a spreadable coating.
The step that matters
Gradually stirring in confectioner's sugar for the icing. Adding the sugar slowly lets the egg white absorb it evenly and build volume and body. Dumping it in at once can leave the icing thin or lumpy, so it will not hold on the layers.
Swap the orange
How well each one fits the dish's main ingredients (sugar, flour, egg):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
