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.

Make the batter

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

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

  3. Stir in the mace for flavor.

  4. Fold in the currants and flour until just combined.

Bake

  1. Pour the batter into pans and bake in a moderate oven at 350°F (175°C) until golden brown.

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 light, tender crumb and rich flavor.
Eggs
Add structure and richness, and help bind the batter as it sets in the oven.
Flour
Forms the cake's structure as its proteins set during baking.
Fine sugar
Sweetens the cake and, creamed with butter, helps create a fine, even texture.
Currants
Add pockets of concentrated sweetness and chewy texture throughout the cake.

The step that matters

Folding in the currants and flour. Overmixing once flour is added develops gluten, which can make the cake tough and dense. Fold gently, just until combined, so the crumb stays tender.

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.
