Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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.
Prepare
Preheat the oven to 400°F (200°C).
Mix the batter
In a bowl, mix the butter, molasses, orange juice, shredded pulp, grated rind, and beaten egg.
Sift the pastry flour with salt and baking powder.
Add the flour mixture alternately with the cold water to the wet ingredients.
Beat well and pour into a shallow pan.
Bake
Bake in the preheated oven until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pastry flour
- Provides the structure that holds the cake together as it bakes.
- Molasses
- Adds sweetness, dark color, and moisture with a deep, rich flavor.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Egg
- Binds the batter and adds structure and richness as it sets.
- Butter
- Adds fat for tenderness and a rich mouthfeel.
- Orange
- Contributes acidity, aroma, and moisture from its juice, pulp, and rind.
The step that matters
Add the flour mixture alternately with the cold water. Adding flour and liquid in alternating portions keeps the batter smooth and evenly hydrated. Overmixing once flour is in develops gluten, which can toughen the cake, so mix only until combined.
Swap the orange
How well each one fits the dish's main ingredients (butter, flour, molasses, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, flour, molasses, egg. Candidates are from the same food group and used in at least 100 recipes.
