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 ↓
Cream Cup Cakes
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 the batter
Preheat the oven to 350°F (175°C).
Cream the butter in a bowl.
Gradually add the sugar, then mix in the grated rind and juice of the orange and the beaten egg yolks.
In a separate bowl, mix and sift the flour, baking soda, and salt.
Add the dry ingredients to the butter mixture, beating constantly.
Cut and fold in the stiffly beaten egg whites until well blended.
Bake
Pour the batter into very small, deep, well-buttered, fluted cake pans.
Bake for twenty minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and adds richness and a tender crumb.
- Egg yolks
- Add richness, moisture and binding to the batter.
- Egg whites
- Whipped and folded in, they trap air that lifts and lightens the cakes.
- Flour
- Forms the structure that holds the cakes together as they set.
- Baking soda
- Reacts with the acidic orange juice to produce gas that helps the cakes rise.
- Sugar
- Sweetens the cakes and helps create a soft, tender texture when creamed with butter.
The step that matters
Cut and fold in the stiffly beaten egg whites. Folding gently keeps the air bubbles in the whipped whites intact. Overmixing deflates them, leaving dense cupcakes instead of light, risen ones.
Swap the orange
How well each one fits the dish's main ingredients (butter, egg, sugar, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
