Citron Cake

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 Cake

Oven, in the book's wordsA moderate oven

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

  1. Preheat the oven to 350°F (175°C).

Make the batter

  1. Beat the butter and sugar until very light.

  2. Add the yolks of the eggs, rose-water, and half of the flour.

  3. Whisk the egg whites until light and fold them in alternately with the remaining flour.

  4. Stir in the floured citron.

Bake

  1. Pour the batter into one large or two small cake pans lined with buttered paper.

  2. Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Creamed with sugar to trap air and add richness and tenderness to the crumb.
Eggs
Yolks add richness and binding, while whipped whites add lift and structure.
Flour
Forms the structure of the cake once mixed and baked.
Sugar
Sweetens the cake and helps aerate the creamed butter.
Citron
Provides the main flavor and bits of candied fruit throughout the cake.

The step that matters

Folding the whipped egg whites. Whites must be folded in gently and alternately with the flour so the batter keeps the air beaten into it. Overmixing deflates the foam, leading to a denser cake.

Swap the nutmeg

How well each one fits the dish's main ingredients (butter, sugar, flour, egg, rose):

  1. Cinnamonfits about as well
  2. Nutmegthe original
  3. Capersfits less well
  4. Allspicefits less well

Fit is the average pairing score against butter, sugar, flour, egg, rose. Candidates are from the same food group and used in at least 100 recipes.
