Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Orange Layer 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.

Make the batter

  1. Beat the egg yolks until thick and creamy.

  2. Add powdered sugar and beat again.

  3. Mix in water, orange juice, part of the grated rind, and sifted flour with baking powder.

  4. Fold in the beaten egg whites.

Bake and ice

  1. Bake in layers at 350°F (175°C).

  2. For icing, beat the egg whites until stiff, then add powdered sugar and the remaining grated orange rind.

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

What each ingredient does

Egg yolks
Add richness and moisture, and help the batter become thick and creamy.
Egg whites
Beaten and folded in to trap air, giving the cake lightness and a open crumb.
Flour
Forms the cake's structure once heated.
Baking powder
Releases gas when heated, helping the layers rise.
Powdered sugar
Sweetens the cake and helps the batter and icing hold their texture.

The step that matters

Fold in the beaten egg whites. Folding gently keeps the air bubbles in the whipped whites. Stirring or deflating them makes the layers dense and flat instead of light.

Swap the orange

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

  1. Raisinfits better
  2. Vanillafits better
  3. Lemonfits better
  4. Orangethe original

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