Delicate and Fruit Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

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

  2. Cream together the sugar and butter.

  3. Add the flour, sweet milk, and Royal Baking Powder, mixing well.

  4. Fold in the egg whites gently.

Make the fruit lining

  1. For the fruit lining, mix 4 tablespoons of dough with raisins, currants, citron, and ½ cup of flour.

  2. Add the molasses or white sugar syrup to the fruit mixture.

Bake and assemble

  1. Bake in layers, placing a fruit layer between two white layers.

  2. Assemble the cake with white icing.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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

Egg whites
Whipped air and protein give the cake lift and a light, open structure as it bakes.
Flour
Its proteins set during baking to form the cake's structure.
Butter
Fat creamed with sugar traps air and gives the crumb a tender, rich texture.
Baking powder
Releases gas when heated, helping the batter rise and become airy.
Sugar
Sweetens the cake and helps tenderize the crumb while creaming with butter.
Molasses
Adds sweetness, moisture, and a deeper flavour to the fruit layer.

The step that matters

Fold in the egg whites gently. Whipped egg whites hold the air that makes the cake rise. Vigorous stirring knocks that air out, leaving a dense, flat cake.

Swap the currant

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

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

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