Oven, in the book's wordsA quick oven

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 together the butter and sugar.

  2. Add the beaten egg, milk, and lemon juice; mix well.

  3. Combine the baking powder with the flour and stir into the mixture.

  4. Fold in the chopped peanuts and add more flour if necessary to make a stiff batter.

Bake

  1. Drop by teaspoonfuls onto buttered baking sheets, spacing them an inch apart.

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

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

What each ingredient does

Butter
Creamed with sugar, it adds richness and tenderness to the cookie.
Granulated sugar
Creams with butter for structure and gives the cookies sweetness and golden browning.
Egg
Binds the batter and adds structure as it sets in the oven.
Baking powder
Releases gas during baking, helping the cookies rise and lighten.
All-purpose flour
Provides the main structure, setting as the cookies bake.
Chopped peanuts
Add nutty flavor and a crunchy texture throughout the cookies.

The step that matters

Adding flour to reach a stiff batter. Too much flour makes the cookies dry and dense, while too little leaves them spreading thin and soft. The batter should hold its shape when dropped from a spoon.

Swap the peanut

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

  1. Almondfits better
  2. Pistachiofits better
  3. Milletfits better
  4. Peanutthe original

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