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 ↓

Layer Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the cake

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

  2. Cream together the sugar and butter until light and fluffy.

  3. Add the milk and egg whites, mixing well.

  4. In a separate bowl, combine the flour, baking soda, and cream of tartar.

  5. Gradually add the dry ingredients to the wet mixture, mixing until smooth.

  6. Pour the batter into prepared cake pans and bake for 25-30 minutes.

Make the filling

  1. For the filling, bring 3 cups of water to a boil.

  2. Dissolve the corn starch in a little water and add it to the boiling water.

  3. Stir in 1½ cups of sugar and the beaten eggs.

  4. Add the juice and rind of the lemons after it boils.

  5. Let the filling cool before using it between the cake layers.

The flavor team

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.

    Shared aroma: isobutyraldehyde (malty, green).

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

Butter
Creams with the sugar to trap air, giving the cake a light, tender crumb and rich flavor.
Egg whites
Add structure and lift to the batter as they set during baking.
Flour
Forms the main structure of the cake as its proteins set in the oven.
Baking soda
Reacts with the acid in the batter to produce gas that helps the cake rise.
Cream of tartar
Acidifies the batter, helping stabilize the egg whites and react with the baking soda.
Corn starch
Thickens the filling as it heats, giving it a smooth, spreadable body.

The step that matters

Let the filling cool before using it between the cake layers. Starch-thickened fillings keep thickening as they cool and set. Spreading it while hot would make it runny and let it soak into or slide off the layers.

Swap the lemon
