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. Preheat the oven to 350°F (175°C).

  2. Beat the butter and sugar together until creamy.

  3. Add the beaten eggs, flour, and floured fruit, mixing well.

  4. Stir in the baking powder last.

  5. Blanch and chop the almonds, and shred the orange peel or citron finely.

  6. Mix everything thoroughly.

Bake

  1. Pour the batter into a well-buttered tin lined with buttered paper.

  2. Bake for 4 hours.

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

What each ingredient does

Butter
Creams with sugar to add richness and a tender crumb.
Sugar
Sweetens the cake and helps the creamed butter hold air for a softer texture.
Eggs
Bind the batter and add structure as the cake sets.
Flour
Forms the main structure of the cake as it bakes.
Baking powder
Releases gas in the wet batter and in the oven, helping the cake rise.
Raisins
Add moisture and chewy sweetness throughout the cake.

The step that matters

Stir in the baking powder last. Baking powder begins releasing gas as soon as it gets wet and warm. Adding it at the end and mixing just until combined keeps that gas in the batter, so the cake rises well instead of going flat or dense.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Lemonfits better
  4. Currantthe original

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