Plum 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

Make the batter

  1. Cream the butter and sugar together until light and fluffy.

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

  3. Stir in the sour cream, baking soda, and spices.

  4. Gradually add the flour, mixing until just combined.

  5. Fold in the raisins and currants.

Bake

  1. Pour the batter into a greased cake pan and smooth the top.

  2. Bake for about 1 hour 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

Butter
Creamed with sugar to trap air, giving the cake a tender, rich crumb.
Eggs
Add structure and richness, binding the batter as it sets in the oven.
Flour
Forms the cake's structure as its proteins set during baking.
Baking soda
Reacts with the acidic sour cream to produce gas that helps the cake rise.
Sour cream
Adds moisture and acidity, tenderising the crumb and activating the baking soda.
Raisins
Add chewy pockets of sweetness and moisture throughout the cake.

The step that matters

Adding the flour. Mixing only until just combined keeps gluten development low, so the cake stays tender rather than tough and dense.

Swap the clove

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Allspicefits better
  4. Clovethe original

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