Why it works: Sorghum and flour share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 99 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Ginger-snaps
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Boil molasses, shortening, salt, and ginger for 2 minutes.
Set aside to cool.
Once cool, add baking soda and mix thoroughly.
Add flour to create a soft dough that can be rolled out thin.
Bake
Cut into shapes and bake in a hot oven at 400°F (200°C) until done.

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 the characteristic deep flavour of the cookies.
- Shortening
- Adds fat for tenderness and a crisp, snappy texture once baked.
- Baking soda
- Reacts with the acidic molasses to lift and lighten the dough, and helps browning.
- Flour
- Provides the structure that lets the dough be rolled thin and hold its cut shapes.
- Ginger
- Supplies the warm, spicy aroma that defines a ginger snap.
The step that matters
Cool before adding baking soda. Baking soda reacts with the acidic molasses right away. If the mixture is still hot, the reaction is fast and gassy, so the dough can lose lift and become uneven. Letting it cool first gives a more controlled rise and a better texture.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sorghum, beef, flour):
- Cinnamonfits better
- Nutmegfits about as well
- Gingerthe original
- Clovefits about as well
Fit is the average pairing score against molasses, sorghum, beef, flour. Candidates are from the same food group and used in at least 100 recipes.
