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

  2. Add the milk and mix well.

  3. Gradually stir in the flour, followed by the chopped raisins, currants, and citron.

  4. In a separate bowl, combine the cream of tartar, baking soda, cinnamon, cloves, and nutmeg.

  5. Add the dry ingredients to the wet mixture and mix until just combined.

Bake

  1. Pour the batter into a greased cake pan and bake for 30-40 minutes or until a toothpick 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, it traps air and adds richness and tender texture.
Flour
Provides the structure that holds the cake together as it bakes.
Baking soda
Reacts with the acidic cream of tartar and molasses to help the cake rise.
Cream of tartar
Acts as an acid that works with baking soda to produce lift and a lighter crumb.
Molasses
Adds moisture, deep flavor, and color, and contributes to browning.
Raisins
Add moisture and chewy sweetness scattered through the crumb.

The step that matters

Mixing the dry ingredients into the wet mixture. Mixing only until just combined keeps gluten development limited, so the cake stays tender rather than tough and dense.

Swap the currant
