Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Hard Molasses Gingerbread
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Mix molasses, lard or butter, salt, ginger, and saleratus in a bowl until well combined.
Add cold water and enough flour to form a dough that can be rolled out.
Shape and bake
Roll the dough very thin and cut into strips about 3 inches wide and 6 inches long.
Use a jagging tool to decorate the edges.
Bake in a 400°F (200°C) oven until brown.
Cool and store
Remove from the oven and cool on a sieve.
Once cooled, store in a tightly covered tin box in a dry place for up to a month.

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
- Provides the dark color, rich flavor and sweetness that define the gingerbread.
- Lard or butter
- Adds fat for tenderness and a short, crisp texture in the baked dough.
- Saleratus
- Reacts to lift the dough and help it spread and brown in the oven.
- Flour
- Forms the structure of the dough so it can be rolled and holds its shape when baked.
The step that matters
Roll the dough very thin. Thin dough bakes through and browns evenly, giving a crisp texture. Thick pieces stay soft and dense in the centre, so the strips may not set properly.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Gingerthe original
Fit is the average pairing score against molasses, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
