Chocolate Cookies

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 ↓

Chocolate 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.

Make the cookie dough

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

  2. Cream the brown sugar and melted butter together.

  3. Add the egg, flour, milk, baking soda, and melted chocolate; mix well.

  4. Fold in the walnuts and raisins.

  5. Drop spoonfuls of the mixture onto buttered baking sheets.

  6. Bake until set.

Make and spread the frosting

  1. For the frosting, combine sugar, grated chocolate, cream, butter, and eggs in a bowl.

  2. Cook the mixture over boiling water until glossy, then beat well.

  3. Spread the frosting over the baked cookies.

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

Eggs
Bind the dough and, in the frosting, thicken the mixture when cooked and give it body.
Brown sugar
Adds sweetness and moisture, and a deeper caramel flavor to the cookies.
Melted butter
Provides fat for tenderness and richness in the cookie dough.
Flour
Provides the structure that holds the cookies together as they bake.
Baking soda
Reacts with the dough to help the cookies rise and spread lightly.
Chocolate
Adds chocolate flavor to both the cookies and the frosting.

The step that matters

Cook the frosting over boiling water until glossy. Gentle heat from the steam lets the eggs thicken without scrambling. Overheating can curdle them, so the frosting must be stirred and kept off direct heat.

Swap the walnut

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits about as well
  4. Walnutthe original

Fit is the average pairing score against sugar, raisin, butter, milk, chocolate, egg, 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.
