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 ↓
Baltimore Ginger Snaps
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, combine molasses, ginger, baking soda, milk, butter, lard, brown sugar, and salt. Mix until well combined.
Gradually add flour until a dough forms that can be rolled out.
Bake
Roll out the dough and cut into very thin cakes.
Bake in a preheated oven at 350°F (175°C) until crisp. The pan does not need to be greased.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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 dark sweetness, moisture and a rich flavour to the dough.
- Baking soda
- Reacts with the molasses's acidity to lighten the dough and help it spread.
- Butter
- Adds fat for flavour and a tender, crisp texture.
- Lard
- Adds fat that helps the cookies stay tender and crisp.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown.
- Flour
- Provides the structure that holds the dough together when rolled.
The step that matters
Roll the dough very thin. Very thin cakes bake through and dry out to a crisp texture. Thicker pieces stay soft in the centre and may not crisp as intended.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, milk, butter, sugar, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Jalapenofits about as well
Fit is the average pairing score against molasses, milk, butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
