Walnut 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.

Prepare

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

Make the batter

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

  2. Add the baking powder and mix well.

  3. Fold in the walnut kernels.

  4. In a separate bowl, beat the egg whites until stiff peaks form.

  5. Gently fold the egg whites into the walnut mixture.

Bake

  1. Pour the batter into a small-sized pan, similar to an almond sponge cake.

  2. Bake until golden brown and a toothpick inserted comes out clean.

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

What each ingredient does

Butter
Creamed with sugar to trap air and add richness and a tender crumb.
Sugar
Creams with butter for a light texture and adds sweetness and browning.
Baking powder
Releases gas in the batter, helping the cake rise.
Egg whites
Whipped to stiff peaks, they add air and structure for a light cake.
Walnut kernels
Add texture, nutty flavor, and fat that keeps the crumb moist.

The step that matters

Gently fold the egg whites into the walnut mixture.. Whipped egg whites hold air that makes the cake light. Stirring vigorously or overmixing knocks that air out, leaving a dense result.

Swap the walnut

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

  1. Almondfits better
  2. Pecansfits better
  3. Filbertfits about as well
  4. Walnutthe original

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