Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make the batter

  1. Cream the butter and sugar together.

  2. Add the spices, molasses, and beaten yolks of the eggs.

  3. Mix in part of the flour and the baking soda.

  4. Fold in the stiffly beaten egg whites.

  5. Gently add the floured fruit and nuts.

Bake

  1. Pour the batter into a greased pan and bake for about 1 hour and 15 minutes.

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

What each ingredient does

Eggs
Yolks enrich the batter, while whipped whites lighten it and help it rise and set.
Butter
Creamed with sugar, it traps air and adds richness and a tender crumb.
Flour
Provides the structure that holds the cake together as it bakes.
Baking soda
Reacts with the molasses's acidity to produce gas that helps the cake rise and brown.
Dark molasses
Adds moisture, deep sweetness, and color to the batter.
Walnut meats
Add texture and a rich, nutty flavor throughout the cake.

The step that matters

Folding in the stiffly beaten egg whites. Whites hold air only if they are beaten stiff and folded in gently. Stirring vigorously deflates them, leaving a denser cake with less lift.

Swap the walnut

How well each one fits the dish's main ingredients (brandy, lemon, butter, orange, sugar, molasses, meat):

  1. Almondfits better
  2. Walnutthe original
  3. Pistachiofits about as well
  4. Chestnutfits about as well

Fit is the average pairing score against brandy, lemon, butter, orange, sugar, molasses, meat. Candidates are from the same food group and used in at least 100 recipes.
