Sour Milk 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. Mix sugar and cocoa in a bowl.

  2. Add butter and cream together until smooth.

  3. Stir in sour milk and flour until well combined.

  4. Add flavoring if desired.

Bake

  1. Pour the batter into a loaf or sheet cake pan.

  2. Bake at 350°F (175°C) until a toothpick comes out clean.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Sugar
Adds sweetness and helps give the cake a tender crumb.
Sour milk
Its acidity reacts with the baking soda to lift the cake and add tang.
Butter
Adds fat for richness, moisture and a tender texture.
Flour
Provides the structure that holds the cake together as it bakes.
Baking soda
Reacts with the acid in the sour milk to produce gas that makes the cake rise.
Cocoa
Adds chocolate flavor and a deep brown color.

The step that matters

Stir in sour milk and flour until well combined. Mix only until the flour is combined. Overmixing develops gluten in the flour, which makes the cake tough and dense rather than tender.

Swap the cocoa

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Cocoathe original

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