Why it works: Flour and raisin 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 ↓
Boston Cookies
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.
Prepare
Preheat the oven to 350°F (175°C).
Make the dough
In a large bowl, mix the butter and sugar until creamy.
Add the flour, chopped raisins, dissolved baking soda, eggs, salt, nutmeg, and flavoring. Mix well.
Shape and bake
Roll the dough thin or drop spoonfuls onto baking pans.
Sprinkle granulated sugar over each cookie.
Bake 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
- Creams with sugar to add fat and tenderness to the cookie texture.
- Sugar
- Sweetens the dough and helps create a crisp, golden surface when baked.
- Flour
- Provides the structure that holds the dough together as it bakes.
- Eggs
- Bind the dough and add structure and richness.
- Baking soda
- Reacts with other ingredients to lift the cookies and encourage browning.
The step that matters
Bake until golden. Cookies keep baking on the hot pan after leaving the oven, so pulling them when the edges are golden keeps them from drying out and becoming hard.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, egg):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against butter, sugar, flour, raisin, egg. 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.
