Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Provides the structure that holds the cookie together as it bakes.
Butter
Adds richness and tenderness, and helps the cookies spread in the pan.
Eggs
Bind the dough and add structure and moisture to the cookies.
Brown sugar
Adds moisture and chewiness, and drives browning during baking.
Soda
Reacts with acidic ingredients to help the cookies rise and spread.
Walnuts
Add crunch and a toasty, nutty flavor that contrasts with the soft dough.

The step that matters

Bake until a rich brown. Sugars and proteins brown through the Maillard reaction, which gives flavor and color. Baking past rich brown dries the cookies and makes them hard.

Swap the nuts

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

  1. Almondfits better
  2. Pistachiofits better
  3. Chestnutfits better
  4. Nutsthe original

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