Boston Cookies

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

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, cream the butter and sugar together.

  3. Add the flour, chopped raisins, baking soda dissolved in warm water, eggs, salt, nutmeg, and any additional flavoring. Mix well.

Shape and bake

  1. Roll the dough thin or drop spoonfuls onto baking sheets.

  2. Sprinkle granulated sugar over each cookie before baking.

  3. Bake until golden brown.

  4. Allow to cool before serving.

The flavor team

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
Creamed with sugar to trap air and give the cookies a tender, rich texture.
Sugar
Sweetens the dough and, creamed with butter, helps create a lighter texture and browning.
Flour
Provides the structure that holds the cookies together as they bake.
Eggs
Bind the dough and add structure and richness.
Baking soda
Reacts to lift the dough and promote spreading and browning.
Chopped raisins
Add chewy moisture and sweetness throughout the cookies.

The step that matters

Dissolving the baking soda in warm water. Baking soda needs to be fully dissolved so it reacts evenly through the dough. Clumps can leave bitter or soapy spots and uneven rising.

Swap the nutmeg

How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, egg):

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Jalapenofits less well
  4. 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.
