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 hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix the milk, flour, baking powder, grated orange rind, and beaten egg until well combined.
Pour the batter into a greased cake pan and bake until golden.
Glaze and finish
In a separate bowl, combine the orange juice and enough boiling water to wet the powdered sugar.
Spread the orange glaze over the cooled cake using a knife dipped in the orange juice.
Allow the glaze to harden in a cool place.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Provides the structure that holds the cake together as it bakes.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Milk
- Adds moisture and hydrates the flour to form the batter.
- Powdered sugar
- Forms a sweet glaze that sets firm as it dries on the cake.
The step that matters
Adding boiling water to the powdered sugar. Only enough boiling water should be added to wet the sugar. Too much thins the glaze so it runs off the cake instead of setting into a coating.
Swap the orange
How well each one fits the dish's main ingredients (milk, flour, egg, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against milk, flour, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
