Portugal 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 the oven to 350°F (175°C).

Make the batter

  1. In a bowl, beat the butter and sugar until light and fluffy.

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

  3. Stir in the mace, currants, and flour until combined.

Bake

  1. Pour the batter into pans and bake for about 30-40 minutes or until golden.

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

What each ingredient does

Butter
Creaming with sugar traps air, giving the cake a light, tender crumb and rich flavor.
Sugar
Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
Eggs
Add structure and richness, binding the batter as the cake sets in the oven.
Flour
Forms the structure of the cake, setting as it bakes.
Currants
Add pockets of sweetness and chewy texture throughout the cake.

The step that matters

Adding the eggs one at a time. Beating each egg in fully before the next keeps the butter-sugar mixture emulsified. If eggs are added too fast, the batter can curdle, which may result in a coarser, denser crumb.

Swap the mace

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

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

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