Fudge Cookies

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 300°F (150°C).

Mix the batter

  1. In a bowl, beat the eggs well.

  2. Add the brown sugar and mix until combined.

  3. Stir in the flour, vanilla, nuts, and melted chocolate.

Bake and cut

  1. Spread the mixture thinly in pans.

  2. Bake for 30 minutes.

  3. Cut into pieces as soon as baked.

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

Eggs
Bind the batter and help set its structure as it bakes.
Brown sugar
Adds sweetness and moisture, contributing to a chewy, fudgy texture.
Flour
Provides the structure that holds the batter together once baked.
Chocolate
Adds fat and rich chocolate flavor that defines the fudgy character.

The step that matters

Cut into pieces as soon as baked. Baked batter continues to firm up as it cools. Cutting while it is still warm, before the sugars and fats set, keeps pieces neat instead of crumbling or tearing.

Swap the nuts

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

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

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