Grandma 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.

Make the dough

  1. Combine sugar and lard in a large mixing bowl until well blended.

  2. Add eggs and mix thoroughly.

  3. Dissolve ammonia in a small amount of water and add to the mixture.

  4. Stir in baking soda, glucose, mace, and lemon.

  5. Gradually add flour until a dough forms.

Shape and bake

  1. Shape the dough into cookies and place on baking sheets.

  2. Bake in a preheated oven at 350°F (175°C) until golden.

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 the cookies brown and crisp at the edges.
Lard
Provides fat for tenderness and richness in the dough.
Eggs
Bind the dough and add moisture and structure to the cookies.
Baking soda
Reacts to lift the dough and promote browning in the oven.
Flour
Forms the structure that holds the cookies together as they bake.

The step that matters

Dissolving the ammonia. Ammonia is a leavening agent that releases gas as it breaks down, so it must be fully dissolved in water before mixing to spread evenly and avoid pockets or uneven rising in the dough.

Swap the mace

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

  1. Nutmegfits better
  2. Cinnamonfits better
  3. Turmericfits better
  4. Macethe original

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