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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, mix sugar, treacle, and butter or lard.
Add vinegar, ginger, and baking soda, then mix well.
Gradually add flour until the dough is firm enough to roll out.
Shape and bake
Roll out the dough and cut into shapes.
Bake in a moderate oven (350°F / 175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and helps the cookies brown and crisp as they bake.
- Treacle
- Adds deep sweetness, dark colour and moisture to the dough.
- Butter or lard
- Provides fat for tenderness and richness in the dough.
- Vinegar
- Adds acidity that reacts with baking soda to help the cookies rise and soften.
- Baking soda
- Reacts with the acid in the dough to produce gas for rising and spreading.
- Flour
- Provides structure so the dough holds its shape when rolled and cut.
The step that matters
Adding the flour. Flour should be added gradually until the dough is firm enough to roll. Too little leaves a sticky dough that is hard to cut, while too much makes the cookies dry and tough because the gluten and starch become overworked and absorb too much liquid.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, butter, vinegar, flour):
- Cinnamonfits better
- Jalapenofits better
- Tarragonfits better
- Gingerthe original
Fit is the average pairing score against sugar, butter, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
