Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the beaten eggs and milk, and mix well.
In a separate bowl, combine the flour, baking powder, and mace.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Bake
Pour the batter into individual tins and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air, giving the cupcakes a light, tender crumb and rich flavor.
- Sugar
- Sweetens the batter and, when creamed with butter, helps create a light, aerated texture.
- Eggs
- Add structure and richness, binding the batter and helping it set as it bakes.
- Flour
- Forms the main structure of the cupcakes as its proteins set during baking.
- Baking powder
- Releases gas during baking, causing the cupcakes to rise and become airy.
- Milk
- Adds moisture and helps hydrate the flour, contributing to a soft texture and browning.
The step that matters
Stirring the dry ingredients into the wet mixture. Stirring only until just combined keeps gluten development low, so the cupcakes stay tender rather than tough. Overmixing after the flour is added develops gluten and can make the crumb dense and chewy.
Swap the mace
How well each one fits the dish's main ingredients (butter, milk, sugar, flour, egg):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Macethe original
Fit is the average pairing score against butter, milk, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
