Why it works: Nutmeg and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 11,917 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Citron Cakes
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix the sugar, lard, molasses, honey, baking soda, eggs, flour, citron, nutmeg, and cinnamon to form a dough.
Let the dough rest for five to six hours before baking.
Shape and bake
Roll out the dough into a sheet and cut it into 2‑inch squares.
Bake in a slow oven at 300°F (150°C) until done.
Glaze and finish
Boil 1½ lbs of sugar to a string consistency, then let it cool slightly.
Brush the cooled sugar over the baked cakes and cut them out as marked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the dough together after baking.
- Eggs
- Add structure and richness, helping the dough bind and set.
- Baking soda
- Reacts with the acidic molasses and honey to help the cakes rise and lighten.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic flavor.
- Honey
- Adds sweetness and moisture that helps keep the cakes soft.
- Lard
- Adds fat for tenderness and a short, moist crumb.
The step that matters
Resting the dough. Resting lets the flour fully hydrate and the dough relax, so the cakes bake more evenly and cut cleanly. Skipping the rest can leave a tougher, less uniform texture.
“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.
