Ingredients

Directions

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

Make the batter

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

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

  3. Add the egg, sweet milk, baking soda, cream of tartar, and lemon flavoring; mix well.

  4. Gradually add the flour and stir until combined.

  5. Divide the batter between two round cake pans.

Bake and assemble

  1. Bake for 25-30 minutes or until a toothpick comes out clean.

  2. Once baked, spread apple sauce or jelly on one cake layer.

  3. Place the second cake layer on top and dust with powdered sugar.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Butter
Creams with the sugar to add fat and a tender crumb.
Baking soda
Reacts with the acid in cream of tartar to produce gas that lifts the batter.
Cream of tartar
Provides acidity that activates the baking soda, helping the cake rise.
Flour
Forms the structure of the cake as the batter sets in the oven.
Egg
Adds structure and richness, helping bind the batter.
Sugar
Sweetens the cake and helps it brown and stay tender.

The step that matters

Gradually add the flour and stir until combined. Overmixing once flour is in develops gluten, which can make the cake tough and dense. Stir just until no dry flour remains.

Swap the apple

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

  1. Vanillafits better
  2. Raisinfits better

  4. Applethe original

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