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

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

Make the batter

  1. In a large bowl, cream together the sugar and butter until light and fluffy.

  2. Add the eggs one at a time, mixing well after each addition.

  3. Stir in the flour, raisins, currants, spices, brandy, cream of tartar, and baking soda until well combined.

  4. Pour the batter into a greased cake pan.

Bake

  1. Bake for 4 hours or until a toothpick inserted in the center comes out clean.

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 during baking.
Butter
Adds fat and richness, and creaming it with sugar traps air for a tender crumb.
Flour
Forms the structure of the cake as its proteins set in the oven.
Sugar
Sweetens the cake and helps keep it moist and tender.
Baking soda
Reacts with the acid in the batter to produce gas that helps the cake rise.
Cream of tartar
Acts as an acid that works with the baking soda to help the cake rise.

The step that matters

Bake for 4 hours or until a toothpick inserted in the center comes out clean.. A long, moderate bake lets heat reach the center of a dense batter without over-browning the outside. Testing the center with a toothpick confirms the structure has fully set, since a cake pulled too early may collapse or be gummy.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Apricotfits about as well
  4. Currantthe original

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