Luncheon 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).

Make the batter

  1. In a large bowl, mix the butter and flour until well combined.

  2. Add the sugar, currants, raisins, and candied peel, and mix thoroughly.

  3. Incorporate the eggs one at a time using your hands until fully combined.

Bake

  1. Pour the mixture into a greased tin and bake for 1½ hours.

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

What each ingredient does

Flour
Provides the structure that holds the cake together as it bakes.
Butter
Adds fat that makes the crumb tender and rich.
Sugar
Adds sweetness and helps tenderise the crumb while creaming with butter.
Eggs
Bind the batter, add moisture and help set the structure as it bakes.
Baking powder
Releases gas in the batter to help the cake rise.

The step that matters

Incorporating the eggs one at a time. Adding eggs gradually lets each one blend fully into the butter and sugar mixture. Adding them too quickly can cause the batter to curdle or separate, which may give a coarser, denser cake.

Swap the currant

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

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

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