Pound Plum Cake

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

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

  2. Soak the raisins, currants, and peels in brandy the day before.

Make the batter

  1. Cream the butter until smooth.

  2. Gradually add the powdered sugar and mix well.

  3. Incorporate the egg yolks one at a time.

  4. Add the soaked fruit and lemon peel to the creamed mixture.

  5. Gradually mix in the flour until combined.

Bake

  1. Pour the batter into a prepared cake pan.

  2. Bake slowly until a toothpick inserted comes out clean.

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

What each ingredient does

Butter
Creams with sugar to build a smooth, tender crumb structure.
Eggs
Yolks add richness and help bind the batter together.
All-purpose flour
Provides the main structure that sets the cake as it bakes.
Powdered sugar
Sweetens the batter and dissolves smoothly into the creamed butter.
Raisins
Add chewy texture and sweetness after soaking in brandy.

The step that matters

Bake slowly until a toothpick inserted comes out clean. A dense, fruit-heavy batter needs low, gentle heat so the centre cooks through before the outside over-browns or dries. Testing with a toothpick confirms it is fully set.

Swap the lemon
