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 ↓

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Cream the butter and sugar together until light and fluffy.

  2. Add the eggs and warm water, mixing well.

  3. Sift the dry ingredients together and then add the nuts, raisins, and currants.

Bake

  1. Drop the stiff batter by the teaspoon onto buttered baking sheets.

  2. Bake in a hot oven at 400°F (200°C) until golden.

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.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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 rich, tender texture.
Sugar
Creamed with butter for a light texture, and adds sweetness and browning.
Eggs
Bind the dough and add structure and moisture to the batter.
Flour
Provides the main structure that holds the cookies together as they bake.
Baking soda
Reacts to lift and lighten the cookies as they bake.

The step that matters

Dropping the stiff batter onto the sheets. Stiff batter holds its shape, but cookies still spread as they bake, so the spoonfuls need space between them and should be roughly even in size for uniform cookies.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Coconutfits better
  4. Currantthe original

Fit is the average pairing score against butter, sugar, egg, flour, cinnamon, nuts, raisin. Candidates are from the same food group and used in at least 100 recipes.
