Chkistmas 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.

Make the dough

  1. Stir together the eggs and sugar for one hour.

  2. Add the pulverized hartshorn and enough flour to make a stiff dough.

Shape and rest

  1. Roll out the dough and cut into shapes.

  2. Keep the cookies in a warm room overnight.

Bake

  1. Sprinkle the pans with anis seed before placing the cookies in.

  2. Bake in a slow oven at 300°F (150°C).

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

What each ingredient does

Eggs
Provide structure and richness, setting the dough as it bakes.
Sugar
Adds sweetness and helps the cookies brown and stay tender.
Pulverized hartshorn
Acts as a leavening agent, releasing gas when heated so the cookies rise and lighten.
Flour
Builds the main structure that holds the cookies in shape.

The step that matters

Bake in a slow oven. Hartshorn releases its leavening gas gradually when heated. A slow oven lets the cookies rise evenly and set without browning too quickly on the outside.
