Peanut Cookies

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Pound the peanuts in a mortar until fine.

  2. Sift together 1 cup of flour, baking powder, and salt.

  3. Cream the butter in a bowl.

Make the dough

  1. Gradually add ½ cup of flour and the pounded peanuts to the butter.

  2. Mix in the beaten egg and milk.

Bake

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

  2. Bake in a moderate oven at 350°F (175°C) until golden.

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 add structure and richness as they set.
Butter
Adds fat for tenderness and a rich flavour.
Baking powder
Releases gas in the oven so the cookies rise and lighten.
All-purpose flour
Forms the main structure that holds the cookies together as they set.
Peanuts
Add nutty flavour and a slightly crunchy texture.

The step that matters

Bake until golden. Browning comes from heat acting on the proteins and sugars in the flour, milk and egg. Colour is a better guide to doneness than time alone, since a dough that is pale stays soft and underbaked, while one left too long turns dry and bitter.

Swap the peanut

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

  1. Almondfits better
  2. Walnutfits better
  3. Pecansfits about as well
  4. Peanutthe original

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