Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. In a bowl, combine the bread sponge, sugar, butter, egg, salt, and enough flour to make a spreadable batter.

  2. Let the batter rise until light.

Shape and bake

  1. Fold in the seeded raisins and spread the mixture in a buttered baking pan.

  2. When the batter is light, sprinkle the top with sugar, cinnamon, and small bits of butter.

  3. Bake in a slow oven at 300°F (150°C) until golden.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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: guaiacol (smoky, sweet).

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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

Bread sponge
Provides the yeasted fermentation that makes the batter rise and turn light.
Egg
Adds structure and richness to the batter as it sets in the oven.
Butter
Adds fat for tenderness and richness, and helps the top brown.
Sugar
Adds sweetness and helps the top turn golden as it bakes.
Flour
Forms the structure of the batter so it spreads yet holds its shape.

The step that matters

Letting the batter rise until light. The batter must rise fully before baking; under-proofed dough bakes dense, while the sponge's yeast needs time and warmth to build gas and lift the batter.

Swap the cinnamon

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

  1. Cinnamonthe original
  2. Nutmegfits about as well
  3. Capersfits less well
  4. Jalapenofits less well

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