Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Raspberry 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. Weigh the packet of blancmange powder and make the weight up to 4 oz with flour.

  3. Separate the yolks and whites of the eggs; beat the sugar into the yolks until thoroughly mixed.

  4. Sift the flour, baking powder, and blancmange powder together.

  5. Whisk the egg whites until stiff, then gently fold them and the flour mixture into the yolk and sugar mixture.

  6. Pour the batter into a greased cake tin and bake for 20 to 30 minutes.

Cool and fill

  1. Once baked, turn the cake onto a sieve to cool completely.

  2. When cool, split the cake in half.

  3. Make butter icing flavored with raspberries that have been rubbed through a sieve.

  4. Spread the butter icing on one half of the cake and place the other half on top.

Ice and decorate

  1. Sift icing sugar into a bowl and mix with enough sieved raspberries to achieve a thick cream consistency.

  2. Pour the raspberry icing in the center of the cake, allowing it to run over the sides.

  3. Once the icing is set, decorate the cake with raspberry butter icing using a piping bag.

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

What each ingredient does

Eggs
Whites trapped by whisking give the sponge its lift, and yolks add richness and structure.
Flour
Provides the structure that holds the sponge once the batter sets in the oven.
Baking powder
Releases gas in the batter, helping the cake rise and become light.
Sugar
Sweetens the cake and helps stabilize the yolks and aerate the batter.
Blancmange powder
Adds flavor and softness, partly replacing flour in the batter.

The step that matters

Folding the whites into the batter. Whisked egg whites hold the air that lifts the sponge. Stirring or deflating them vigorously knocks out air, leaving a denser, flatter cake.

Swap the raspberry

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

  1. Raisinfits better

  3. Figfits better
  4. Raspberrythe original

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