Imperial Cake

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the batter

  1. Preheat the oven to 400°F (200°C).

  2. In a bowl, cream the butter and sugar together.

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

  4. Stir in the flour, baking soda dissolved in hot water, currants, lemon rind, lemon juice, and cinnamon.

Bake

  1. Drop spoonfuls of the mixture onto well-buttered parchment paper in a baking pan.

  2. Bake until golden brown.

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

What each ingredient does

Butter
Creams with sugar to trap air and add richness and tender texture.
Eggs
Add structure and binding, helping the batter hold together as it bakes.
Flour
Provides the main structure that sets as the cakes bake.
Baking soda
Reacts with the acidity of the lemon to produce gas that helps the cakes rise.
Sugar
Creaming with butter adds air, and sugar browns during baking for color and sweetness.

The step that matters

Bake until golden brown. Baking soda needs an acid to react, and it works best once the batter is in the oven. Too little baking lets the cakes stay raw and dense inside, while overbaking dries them out and darkens them too far. Watch the color and do not rely on time alone.

Swap the currant

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

  4. Currantthe original

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