Coffee Fruit Cake

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. Cream the butter and sugar together.

  2. Add the spices and molasses, and beat for 5 minutes.

  3. Incorporate the well-beaten egg yolks and coffee.

  4. Gradually add the sifted flour and dissolved baking soda.

  5. Fold in the stiffly beaten egg whites.

Add the fruit

  1. Toss the chopped citron and flour with the raisins and currants.

  2. Add the mixture to the batter.

Bake

  1. Bake in a moderate oven at 350°F (175°C) until done.

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

What each ingredient does

Flour
Builds the cake's structure as its proteins set during baking.
Eggs
Egg whites add lift and structure, while yolks add richness and tenderness.
Butter
Fat coats flour particles, giving the cake a tender, rich crumb.
Sugar
Sweetens the batter and helps keep the cake moist and tender.
Molasses
Adds moisture, dark color, and a deep sweet flavor, and reacts with the baking soda.
Baking soda
Reacts with the acidic molasses to produce gas that helps the cake rise.

The step that matters

Fold in the stiffly beaten egg whites. Folding gently keeps the air in the whites. Stirring or beating them in would deflate the batter, leaving a denser cake with less rise.

Swap the mace

How well each one fits the dish's main ingredients (butter, egg, sugar, coffee, clove, flour, cinnamon):

  1. Nutmegfits better
  2. Cardamomfits better
  3. Allspicefits better
  4. Macethe original

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