Citron 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 together until light and fluffy.

  2. Add the milk and mix well.

  3. Gradually add the flour and baking soda, mixing until combined.

  4. Incorporate the eggs one at a time, mixing well after each addition.

  5. Fold in the sliced citron.

Bake

  1. Pour the batter into a greased cake pan and bake at 350°F (175°C) until a toothpick comes out clean.

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, giving the cake a tender, rich crumb.
Eggs
Add structure and richness, helping the batter set as it bakes.
Flour
Forms the main structure of the cake as its proteins set in the oven.
Baking soda
Reacts with the batter to release gas, helping the cake rise.
Sugar
Sweetens the cake and helps hold air in the creamed butter.

The step that matters

Adding the eggs one at a time. Adding eggs gradually and mixing well after each one lets the emulsion form evenly. A batter that curdles or separates can bake up dense and uneven.
