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 dough

  1. In a bowl, mix the sugar and eggs until well combined.

  2. Add the baking powder and softened butter, mixing until smooth.

  3. Gradually add flour until a dough forms.

  4. Fold in the walnut kernels.

Bake

  1. Shape the dough and place it on a baking sheet.

  2. Bake in the preheated oven until golden brown.

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

What each ingredient does

Eggs
Bind the batter and add structure as they set during baking.
Butter
Adds richness and tenderness to the dough.
Baking powder
Releases gas that makes the cake rise and become light.
Flour
Forms the dough and provides the main structure once baked.
Sugar
Sweetens the dough and helps it brown as it bakes.
Walnut kernels
Add crunch and nutty flavor throughout the dough.

The step that matters

Gradually add flour until a dough forms. Adding flour gradually lets you judge the dough's consistency, since too much flour makes the cake dense and dry while too little leaves it sticky and hard to shape.

Swap the walnut

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

  1. Almondfits better
  2. Macadamia nutfits better
  3. Chestnutfits about as well
  4. Walnutthe original

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