Coffee Cakes

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 ↓

Coffee Cakes

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.

Make the batter

  1. Whisk the eggs, sugar, and coffee essence together in a bowl until frothy and thick.

  2. Melt the butter and stir it in lightly.

  3. Sift the flour and baking powder together, then gently fold them into the mixture.

Bake and finish

  1. Grease about ten small cake tins with clarified butter.

  2. Fill the tins three-quarters full with the batter.

  3. Bake in a moderate oven at 350°F (175°C) for about fifteen minutes.

  4. Let the cakes cool.

  5. Icing with coffee glace icing, if desired.

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

What each ingredient does

Eggs
Whisked with sugar, they trap air and give the cakes their light, airy structure.
Flour
Sets the cake's structure as the batter bakes, holding the risen crumb in place.
Baking powder
Releases gas when heated, helping the cakes rise in the oven.
Butter
Adds richness and a tender texture to the crumb.
Sugar
Sweetens the cakes and helps whisk the eggs into a stable, thick foam.
Coffee essence
Gives the cakes their coffee flavour throughout the batter.

The step that matters

Fold in the flour and baking powder gently. Overmixing knocks out the air whisked into the eggs and develops gluten in the flour, which makes the cakes dense instead of light and airy.
