Bran Cookies

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

Make the dough

  1. In a bowl, mix the bran, sugar, egg, melted butter, sour milk, baking soda, and ginger.

  2. Add flour gradually until the mixture thickens.

Bake

  1. Drop spoonfuls of the mixture onto buttered baking sheets.

  2. Bake for 12-15 minutes or until golden.

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

What each ingredient does

Bran
Adds fibre and body, giving the cookies a hearty, slightly grainy texture.
Egg
Binds the mixture and adds structure and richness as it sets in the oven.
Sour milk
Its acidity reacts with baking soda to help the cookies rise and stay tender.
Baking soda
Reacts with the acidic sour milk to produce gas that leavens the dough.
Sugar
Sweetens the cookies and helps them brown as they bake.
Melted butter
Adds fat for moisture and a rich flavour.

The step that matters

Add flour gradually until the mixture thickens. Flour absorbs liquid and sets the dough's structure. Adding it too quickly can make the dough stiff or uneven, while adding too little leaves the drops spreading thin in the oven.

Swap the ginger

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. Gingerthe original

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