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 ↓

Washington Pie

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.

Prepare

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

Make the batter

  1. Beat sugar and eggs together until well combined.

  2. Sift flour and baking powder into the mixture and mix until smooth.

  3. Divide the batter into layers.

Bake and assemble

  1. Bake until golden, similar to a jelly cake.

  2. Once cooled, spread raspberry jam between the layers.

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.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
Provide structure and lift, setting the sponge as it bakes.
Flour
Forms the structure that holds the sponge's crumb together.
Sugar
Sweetens the cake and helps it brown as it bakes.
Baking powder
Releases gas in the batter, helping the layers rise.
Raspberry jam
Adds sweetness and fruity flavour between the layers.

The step that matters

Beating the sugar and eggs until well combined. Whisking air into the eggs and sugar gives the batter its lift before the flour goes in. If the mixture is under-beaten, the layers may come out dense, and folding in the flour too roughly can knock out that air.

Swap the raspberry

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

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

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

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
