Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the dough
In a large bowl, mix the sugar, lard, molasses, and water until well combined.
Add the baking soda and flour, mixing until a dough forms.
Stir in lemon flavor or lemon rind.
Shape and bake
Drop the mixture into small greased and dusted scalloped molds.
Bake in the preheated oven until golden.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Molasses
- Adds sweetness, moisture and a deep flavor that also helps the cookies brown.
- Baking soda
- Reacts with the molasses acidity to produce gas, helping the cookies rise and lighten.
- Flour
- Provides the structure that holds the dough together as it bakes.
- Lard
- Adds fat that gives the cookies a tender texture and rich mouthfeel.
- Sugar
- Sweetens the dough and contributes to browning and a crisp edge.
The step that matters
Bake until golden. Molasses and sugar brown quickly at high heat, so the cookies can over-darken or turn bitter before they are set. Watching for golden color rather than just the clock keeps them tender and evenly baked.

Fit is the average pairing score against sugar, molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
