Why it works: Milk and flour 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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the yolks of 4 eggs with 1 cup of granulated sugar until creamy.
Add the beaten whites of 2 eggs. Mix well.
Alternately add ½ cup of milk and 1½ cups of sifted flour mixed with 1½ teaspoons of baking powder. Beat well.
Pour into prepared pans.
Bake and fill
Bake in a preheated oven at 400°F (200°C) for 7 to 10 minutes, or until a straw comes out clean.
Beat the whites of 2 eggs to a stiff froth. Gradually add 1 cup of powdered sugar.
Mix in the grated rind and juice of 1 orange until thick and creamy.
Spread the filling on the hot cake. Reserve some filling for frosting.
Frost
Add about ½ cup of powdered sugar to the reserved filling to harden for frosting.
Ice the top and sides of the cake.

Milk and flour 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
- Egg yolks
- Add richness and structure to the batter while helping it set.
- Egg whites
- Beaten to a stiff froth, they trap air and give the cake and filling lift.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Granulated sugar
- Sweetens the batter and helps trap air when beaten with the yolks.
- Orange rind and juice
- Add citrus aroma and acidity to the filling.
The step that matters
Baking the cake. Baking time is short at a high heat, so the cake can brown or dry out quickly. Check for doneness with a straw at the earliest time, because overbaking makes the crumb dry and tough.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
