Pennsylvania 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 large bowl, cream together the brown sugar and shortening.

  2. Beat in the eggs one at a time.

  3. Stir in the sour milk and baking soda.

  4. Add the cloves, allspice, and cinnamon, mixing well.

  5. Gradually add flour until a soft dough forms.

  6. Fold in raisins to your preference.

Bake

  1. Drop spoonfuls of dough onto a baking sheet.

  2. Bake for 10-12 minutes or until lightly browned.

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

What each ingredient does

Brown sugar
Adds sweetness and moisture, and helps the cookies brown and stay soft.
Shortening
Provides fat that tenderizes the dough and gives the cookies a soft texture.
Eggs
Bind the dough and add structure and richness to the cookies.
Sour milk
Adds moisture and acidity that reacts with the baking soda to help the cookies rise.
Baking soda
Reacts with the acidic sour milk to produce gas that leavens the cookies.
Flour
Forms the structure of the dough once it is mixed in gradually.

The step that matters

Gradually add flour until a soft dough forms. Adding too much flour makes the dough stiff and dry, producing dense, tough cookies. Stopping when the dough is soft keeps the cookies tender.

Swap the clove

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

  1. Nutmegfits better
  2. Cardamomfits about as well
  3. Clovethe original
  4. Gingerfits less well

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