Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Citron Pound Cake
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
Wash the citron in warm water and dry it on a towel.
Cut the citron into thin pieces and chop it very fine.
Butter and line a baking pan with parchment paper.
Make the batter
In a large bowl, combine the butter, sugar, flour, eggs, rose water, brandy, and nutmeg.
Add the chopped citron last and mix well.
Pour the batter into the pan and smooth the top with a knife.
Bake
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as they set during baking.
- Butter
- Adds fat for a tender crumb and rich flavor.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Loaf sugar
- Sweetens the cake and helps it brown as it bakes.
- Citron
- Adds candied-fruit flavor and moisture throughout the cake.
The step that matters
Chopping the citron very fine. Large citron pieces are heavy and can sink to the bottom or leave wet pockets, so fine chopping distributes them evenly through the batter.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, rose, brandy):
- Cinnamonfits about as well
- Nutmegthe original
- Allspicefits less well
- Clovefits less well
Fit is the average pairing score against butter, sugar, flour, egg, rose, brandy. Candidates are from the same food group and used in at least 100 recipes.
