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.

Make the batter

  1. Cream the butter and sugar together.

  2. Add the egg whites and sweet milk, mixing well.

  3. In a separate bowl, combine flour, baking powder, chopped walnuts, vanilla, cornstarch, and salt.

  4. Gradually add the dry ingredients to the wet mixture, stirring until smooth.

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

Egg whites
Add structure and lift to the batter as they set in the oven.
Butter
Adds fat and tenderness, and creaming it with sugar traps air for a lighter crumb.
Sugar
Sweetens the cake and helps tenderize it when creamed with butter.
Flour
Forms the main structure of the cake as its proteins set during baking.
Baking powder
Releases gas in the batter to make the cake rise.
Cornstarch
Softens the crumb by diluting the flour's gluten, giving a finer texture.

The step that matters

Gradually add the dry ingredients to the wet mixture, stirring until smooth.. Adding dry ingredients gradually and mixing only until smooth prevents lumps and limits gluten development, which keeps the cake tender rather than tough.

Swap the walnut

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

  1. Almondfits better
  2. Chestnutfits better
  3. Hazelnutfits better
  4. Walnutthe original

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