Imperial, Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the batter

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

  2. Add the grated lemon rind, baking soda, and lemon juice; mix well.

  3. Incorporate the beaten eggs gradually, mixing thoroughly.

  4. Fold in the flour and chopped walnuts.

  5. Dust the raisins with the extra tablespoon of flour and fold them into the batter.

Bake

  1. Pour the batter into a greased cake pan and bake for 1½ hours.

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 and gives the cake a tender, rich crumb.
Eggs
Bind the batter and add structure and richness as the cake bakes.
All-purpose flour
Forms the gluten network that gives the cake its structure.
Baking soda
Reacts with the acid in the lemon juice to lift the batter as it bakes.
Sugar
Sweetens the cake and helps trap air when creamed with butter.
Raisins
Add moisture and chewy sweetness throughout the cake.

The step that matters

Dust the raisins with flour. Lightly coating the raisins in flour helps keep them suspended in the batter instead of sinking to the bottom during baking.
