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 cake
Beat the egg yolks with granulated sugar until creamy.
Add the beaten egg whites and mix well.
Alternately add milk and sifted flour mixed with baking powder, beating well.
Bake in a 400°F (200°C) oven for 7 to 10 minutes in three large or four small layers.
Check with a broom straw; remove from oven when it comes out clean.
Make the filling and frost
For the filling, beat the egg whites to a stiff froth, then add powdered sugar all at once and beat hard.
Mix in the grated rind and juice of the orange until thick like cream.
Spread the filling on the hot cake.
Mix remaining filling with enough powdered sugar 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
- Eggs
- Yolks enrich the batter and beaten whites give the cake and filling lift and structure.
- Granulated sugar
- Sweetens the batter and helps the beaten yolks form a creamy, stable base.
- Milk
- Adds moisture to the batter, keeping the cake tender.
- Flour
- Forms the main structure that holds the cake's crumb together.
- Baking powder
- Releases gas in the oven so the layers rise.
- Orange
- Rind adds aroma and juice adds acidity and flavour to the filling.
The step that matters
Check the cake with a broom straw. Baking too long dries the crumb, while removing it too early leaves wet batter. A straw that comes out clean shows the structure has set.
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.
