Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

Make the batter

  1. Beat the butter and sugar together until creamy.

  2. Add the eggs, beating them separately before incorporating.

  3. Sift the cream of tartar with the flour and add to the mixture.

  4. Dissolve the baking soda in the milk and mix in.

Bake

  1. Pour the batter into a prepared baking pan and bake until golden.

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

What each ingredient does

Eggs
Beaten eggs trap air and provide structure that sets the sponge's crumb.
All-purpose flour
Provides the starch and gluten that build the cake's structure as it bakes.
Granulated sugar
Sweetens the cake and, creamed with butter, helps trap air for a light texture.
Unsalted butter
Adds fat for tenderness and flavor, and creaming it with sugar aerates the batter.
Baking soda
Reacts with the acid in the cream of tartar to produce gas that helps the cake rise.
Cream of tartar
Acts as an acid that works with the baking soda to leaven the batter and stabilize the eggs.

The step that matters

Beating the eggs separately before incorporating. Beating eggs separately and folding them in gently keeps air in the batter. Overmixing after adding flour can develop too much gluten, making the sponge dense and tough.
