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.

Mix the batter

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

  2. In a large bowl, cream together the butter and sugar until light and fluffy.

  3. Add the molasses and milk, mixing well.

  4. In another bowl, combine the flour, baking soda, cloves, cinnamon, and allspice.

  5. Gradually add the dry ingredients to the wet mixture, stirring until just combined.

  6. Fold in the chopped raisins, currants, and citron until evenly distributed.

Bake

  1. Pour the batter into a deep baking pan.

  2. Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

    Shared aroma: guaiacol (smoky, sweet).

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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

Butter
Creamed with sugar to trap air and give the cake a tender, rich crumb.
Sugar
Creams with butter for a light texture and adds sweetness and gentle browning.
Molasses
Adds deep sweetness, dark color, and moisture to the cake.
Flour
Provides the structure that holds the cake and fruit together as it bakes.
Eggs
Bind the batter and add structure and richness as the cake sets.
Baking soda
Reacts with the acidic molasses to help the cake rise and lighten.

The step that matters

Gradually add the dry ingredients to the wet mixture, stirring until just combined.. Once flour meets liquid, gluten begins to form, so overmixing can make the cake tough and dense. Stop stirring as soon as no dry flour streaks remain.

Swap the clove

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

  1. Nutmegfits better
  2. Cardamomfits about as well
  3. Clovethe original
  4. Allspicefits about as well

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