Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Beat the egg and sugar together until very light.

  2. Add the flour and chopped nuts, mixing well.

Bake

  1. Drop the mixture by teaspoonfuls onto a baking pan, spacing them 1½ inches apart.

  2. Bake in a slow oven at 300°F (150°C) for about twenty minutes.

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

What each ingredient does

Egg
Binds the mixture and adds structure as it sets in the oven.
Sugar
Sweetens the cookies and, beaten with the egg, helps create a light texture.
Flour
Provides the structure that holds the cookies together as they bake.
Nuts
Add flavour, fat and body to the dough.

The step that matters

Beat the egg and sugar until very light. Beating incorporates air into the egg and sugar, which gives the cookies lightness. Under-beaten batter bakes up denser and flatter than intended.

Swap the nuts

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

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

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