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 ↓
Ginger Snaps
Ingredients
Directions
Make the dough
Boil the molasses and let it cool to milk-warm.
Beat in the egg and the melted butter and lard.
Add the ginger and mix well.
Dissolve the baking soda in hot water and add it to the mixture.
Incorporate enough sifted flour to make a dough that can be rolled out easily.
Bake and cool
Roll the dough wafer thin, stamp out the snaps, and bake quickly.
Carefully remove from the pan and lay on sheets of paper until cold and crispy.

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, sweetness and characteristic flavor, and adds moisture to the dough.
- Butter and lard
- Adds fat that tenderizes the dough and gives a rich mouthfeel.
- Baking soda
- Reacts with the molasses's acidity to lighten the dough and help the snaps spread and crisp.
- Flour
- Builds the structure that lets the dough be rolled thin and hold its shape.
- Ginger
- Supplies the spicy aroma and warmth that define the snap.
The step that matters
Roll the dough wafer thin and bake quickly. Thin dough has little water and sugar to hold, so it dries and crisps in a short bake. Thicker pieces stay soft and chewy, and a long bake can scorch the high-sugar molasses before the centre sets.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, egg, butter, flour):

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