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 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
Combine sugar and lard in a large mixing bowl until well blended.
Add eggs and mix thoroughly.
Dissolve ammonia in a small amount of water and add to the mixture.
Stir in baking soda, glucose, mace, and lemon.
Gradually add flour until a dough forms.
Shape and bake
Shape the dough into cookies and place on baking sheets.
Bake in a preheated oven at 350°F (175°C) until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- 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):
- Nutmegfits better
- Cinnamonfits better
- Turmericfits better
- 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.
“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.
