Why it works: Flour and anise work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 270 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Christmas Cookies
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
In a large bowl, stir together the eggs and sugar for one hour.
Add the pulverized hartshorn and enough flour to form a stiff dough.
Roll out the dough and cut into desired shapes.
Place the cookies in a warm room overnight.
Bake
Preheat the oven to 300°F (150°C).
Sprinkle the baking pans with anise seed before placing the cookies in.
Bake the cookies until lightly golden.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add moisture and structure as they are beaten with sugar.
- Sugar
- Adds sweetness and, when beaten with eggs, helps create a light texture.
- Pulverized hartshorn
- Acts as a leavening agent, releasing gas to help the cookies rise and lighten.
- Flour
- Provides structure, setting the dough into a stiff shape that holds cut designs.
The step that matters
Place the cookies in a warm room overnight. Resting shaped dough in a warm place lets the leavening act slowly before baking, so the cookies can rise and set evenly in the oven.
Swap the anise
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Jalapenofits better
- Cinnamonfits better
- Nutmegfits better
- Anisethe original
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
