Fudge 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 cake batter

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

  2. Cream the butter and sugar together in a bowl.

  3. Add the milk and mix well.

  4. Sift the baking powder with the flour and gradually add to the mixture.

  5. Stir in the melted chocolate and coarsely chopped walnuts.

  6. Beat the egg yolks and whites separately, then fold them into the batter.

Bake and make the frosting

  1. Pour the batter into a greased cake pan and bake for about 30-35 minutes.

  2. For the frosting, melt the butter in a saucepan.

  3. Add the chocolate, sugar, salt, and milk, then bring to a boil for 8-10 minutes.

  4. Remove from heat, stir in the vanilla, and beat until smooth.

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 create a tender, aerated crumb and adds richness.
Eggs
Separated and folded in to add structure and lift to the batter.
Baking powder
Releases gas during baking so the cake rises and becomes light.
Flour
Provides the structure that holds the cake together as it sets.
Chocolate
Adds chocolate flavor and color to both the cake and the frosting.
Sugar
Sweetens the cake and, when creamed, helps trap air for a lighter texture.

The step that matters

Beating the egg whites and folding them in. Whites beaten separately and folded gently keep air in the batter. Stirring them in hard knocks that air out, leaving a denser cake.

Swap the walnut

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

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

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