Why it works: Flour and sugar 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 ↓

Lemon Cake

Oven, in the book's wordsA moderately hot oven

Ingredients

Directions

The book says “a moderately hot 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. Whisk the yolks of the eggs in a bowl.

  2. Gradually add the powdered sugar, lemon juice, and grated lemon rind.

  3. Mix in the flour.

  4. In a separate bowl, beat the egg whites to a froth and fold them into the mixture.

Bake

  1. Pour the batter into a warmed and buttered tin mold.

  2. Bake for 1 hour.

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

What each ingredient does

Eggs
Whipped whites trap air for lift, while the yolks add richness and help bind the batter.
Flour
Provides the starch and gluten that set the crumb structure as the cake bakes.
Powdered sugar
Sweetens the cake and dissolves easily, giving a fine, tender crumb.
Lemon
Lemon juice adds acidity and the grated rind adds bright aroma.

The step that matters

Folding in the egg whites. Whites beaten to a froth hold air that gives the cake its rise. Stirring them in vigorously or letting them sit deflates the foam, so the cake bakes up dense and flat. Fold gently and quickly until just combined.

Swap the lemon

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

  1. Raisinfits better
  2. Vanillafits better
  3. Lemonthe original
  4. Figfits about as well

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