Republican 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 the oven to 300°F (150°C).

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

  3. Add the egg yolks and mix well.

Make the batter

  1. Stir in the flour, raisins, currants, and citron.

  2. In a separate bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.

  3. Add the brandy and mix until combined.

Bake

  1. Pour the batter into a greased cake pan and bake for 2 hours.

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

What each ingredient does

Eggs
Yolks enrich and bind the batter, while whipped whites lighten its crumb.
Butter
Creaming with sugar traps air and gives the cake a tender, rich texture.
All-purpose flour
Its proteins set during baking to form the cake's structure.
Brown sugar
Adds sweetness, moisture, and a caramel-like flavor to the crumb.
Raisins
Provide chewy pockets of sweetness and moisture throughout the cake.

The step that matters

Folding in the egg whites. Whites beaten to stiff peaks hold the air that lightens the batter. Stirring them vigorously knocks that air out, leaving a dense cake, so fold gently and only until no white streaks remain.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Apricotfits about as well
  4. Currantthe original

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