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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a bowl, beat the eggs until light.
Add the sugar and mix well.
Sift in the flour and baking powder, then stir to combine.
Add the orange flavoring and boiling milk, mixing until smooth.
Pour the batter into a greased cake pan.
Bake and ice
Bake for about 30-35 minutes or until a toothpick comes out clean.
For the icing, mix powdered sugar with orange juice and a little pulp until smooth.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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 eggs trap air and set during baking, giving the cake its structure.
- Flour
- Sets during baking to form the cake's main structure.
- Sugar
- Sweetens the batter and helps keep the crumb tender and moist.
- Baking powder
- Releases gas when heated, lifting the batter so the cake rises.
- Boiling milk
- Adds moisture and helps make the batter smooth and tender.
- Orange flavoring
- Gives the cake its orange aroma and flavor.
The step that matters
Stop mixing once the flour is in. Once flour is added, overmixing develops gluten, which makes the cake tough and dense. Stir only until the flour disappears into the batter, then add the boiling milk and mix just until smooth.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, flour, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
