Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Prune Coffee 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.

Prepare the batter

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

  2. In a bowl, beat the eggs and add the sugar.

  3. Sift together the flour and baking powder, then gradually add to the egg mixture with the milk, beating until smooth.

  4. Stir in the melted shortening and vanilla extract.

Bake

  1. Pour the batter into two greased layer cake pans.

  2. Cover the top with uncooked pitted prunes and sprinkle with nuts.

  3. Bake for 20 minutes or until golden brown.

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.

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 add structure as they set in the oven.
Flour
Forms the main structure of the cake as it bakes.
Baking powder
Releases gas in the batter so the cake rises and becomes light.
Shortening
Adds fat that tenderizes the crumb and carries flavour.
Sugar
Sweetens the cake and helps it brown during baking.
Milk
Adds moisture and liquid that hydrates the flour into batter.

The step that matters

Beating the batter until smooth after adding the flour. Overbeating flour mixed with liquid develops gluten, which can make the cake tough. Stop mixing once the batter is smooth so the crumb stays tender.

Swap the nuts

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

  1. Almondfits better
  2. Chestnutfits better
  3. Hazelnutfits better
  4. Nutsthe original

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