Walnut 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 your oven to 350°F (175°C).

Make the dough

  1. In a bowl, mix the chopped walnuts, sugar, beaten egg, milk, and baking powder.

  2. Add enough flour to form a dough that can be rolled very thin.

Shape and finish

  1. Roll out the dough and cut into desired shapes.

  2. Brush the cookies with egg white and sprinkle with powdered sugar while warm.

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.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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

Flour
Provides the structure that holds the dough together when rolled thin.
Eggs
Bind the dough and add structure as they set in the oven.
Baking powder
Releases gas in the dough, helping the cookies rise and lighten.
Sugar
Adds sweetness and helps the cookies brown at the edges.
Chopped walnuts
Add texture and a nutty flavor to the cookie.
Milk
Adds moisture so the dough can be mixed and rolled.

The step that matters

Add enough flour to form a dough that can be rolled very thin.. Flour absorbs liquid and forms gluten, so adding too much makes the dough dry and tough, while too little leaves it sticky and hard to roll thin.

Swap the walnut

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

  1. Almondfits better
  2. Milletfits better
  3. Chestnutfits better
  4. Walnutthe original

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