Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

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
Stir together the eggs and sugar for one hour.
Add the pulverized hartshorn and enough flour to make a stiff dough.
Shape and rest
Roll out the dough and cut into shapes.
Keep the cookies in a warm room overnight.
Bake
Sprinkle the pans with anis seed before placing the cookies in.
Bake in a slow oven at 300°F (150°C).

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
- 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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
