Lemon Cake

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 ↓

Lemon Cake

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the lemon filling

  1. Grate the rind of the lemon and squeeze the juice.

  2. Combine lemon juice, grated rind, 1 cup sugar, 1 egg, and butter in a saucepan.

  3. Boil until thick and set aside to cool.

Make and bake the cake

  1. Beat 3 eggs lightly.

  2. Add 1 cup sugar, 1½ cups flour, cream of tartar, baking soda, and milk. Mix well.

  3. Pour batter into well-buttered jelly cake tins.

  4. Bake at 350°F (175°C) until golden.

  5. Spread the lemon mixture between the layers of cake.

Make the icing

  1. Beat the egg white lightly.

  2. Mix in 1 cup sugar.

  3. Flavor with lemon until smooth.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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 set the structure of the cake as they cook.
Flour
Forms the structure of the cake crumb as it bakes.
Sugar
Sweetens the cake and helps it brown as it bakes.
Butter
Adds richness and tenderness to the lemon filling.
Cream of tartar
Acid that reacts with baking soda to help the cake rise.
Baking soda
Releases gas with the acid in the batter to lighten the cake.

The step that matters

Boil the lemon mixture until thick. Egg yolks in the filling can scramble if overheated, so it should be cooked gently and stirred to thicken smoothly rather than curdle.

Swap the lemon
