Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Orange 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 the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs and sugar until light and fluffy.
Add the milk and mix well.
In a separate bowl, combine the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.
Make the frosting and finish
For the frosting, beat the egg whites until stiff peaks form.
Gradually add the powdered sugar, then mix in the orange juice and grated rind.
Spread the frosting over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten with sugar to trap air, giving the cake lift and a light, fluffy crumb.
- All-purpose flour
- Forms the structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter, causing the cake to rise.
- Sugar
- Sweetens the cake and helps hold air when beaten with the eggs, adding tenderness.
- Egg whites
- Whipped to stiff peaks to create a light, stable frosting.
- Orange juice and rind
- Add acidity and citrus aroma to the frosting.
The step that matters
Folding in the dry ingredients. Adding the flour mixture gradually and stirring only until smooth keeps the batter from being overmixed. Overmixing develops gluten, which can make the cake tough and dense.
Swap the orange
How well each one fits the dish's main ingredients (sugar, flour, milk, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
