Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the filling
In a bowl, combine molasses, sugar, milk, eggs, and butter.
Mix well and add your choice of ginger, orange, or lemon for flavor.
Bake
Pour the mixture into a pie crust.
Bake until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the dark color and rich, slightly bitter sweetness that defines the pie.
- Eggs
- Set the filling as they cook, giving the pie a firm, sliceable structure.
- Sugar
- Adds sweetness and helps the filling brown slightly during baking.
- Milk
- Adds moisture and softness to the filling, balancing the thick molasses.
- Butter
- Adds fat for a smooth, rich texture and mouthfeel.
The step that matters
Bake until set. Eggs thicken as their proteins coagulate with heat. Underbaking leaves a runny center, while overbaking can make the filling weep or crack, so watch for a set edge with a slight wobble in the middle.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, milk, egg, butter):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Clovefits about as well
Fit is the average pairing score against molasses, sugar, milk, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
