Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Cream together the sugar and butter until smooth.
Add the beaten eggs and molasses, mixing well.
Stir in the dissolved baking soda, raisins, currants, and mixed spices.
Gradually add flour until the dough is stiff enough to roll.
Shape and bake
Roll out the dough and cut into desired shapes.
Bake in a moderate oven at 350°F (175°C) until golden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Butter
- Adds fat that creams with sugar to make a tender, rich crumb.
- Eggs
- Bind the dough and add structure and richness as they set in the oven.
- Molasses
- Adds moisture, dark color, and a deep sweetness with mild acidity.
- Baking soda
- Reacts with the molasses acidity to lift the cookies and help browning.
- Flour
- Provides the structure that lets the dough be stiff enough to roll and cut.
The step that matters
Gradually add flour until the dough is stiff enough to roll. Adding too much flour makes cookies dry and tough, while too little leaves dough sticky and hard to cut. Adding it gradually lets you stop when the dough reaches a rollable stiffness.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, egg, molasses, raisin, flour):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against sugar, butter, egg, molasses, raisin, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
