Peanut Cookies

Oven, in the book's wordsA slow oven

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. Cream the butter in a bowl.

  2. Add the sugar and well-beaten egg, mixing until combined.

  3. Sift together the dry ingredients and add to the butter mixture.

  4. Stir in the milk, chopped peanuts, and lemon juice.

Shape and bake

  1. Drop teaspoonfuls of the mixture onto an unbuttered baking sheet, spacing them one inch apart.

  2. Place half a peanut on top of each cookie.

  3. Bake in a cool oven at 300°F (150°C) for 12 to 15 minutes.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Butter
Creams with the sugar to add richness and tenderness to the cookie.
Egg
Binds the dough and adds structure as it sets in the oven.
Baking powder
Releases gas during baking so the cookies rise and turn light.
Flour
Forms the main structure of the cookie as its proteins and starches set.
Peanuts
Add crunch and a nutty flavor throughout the cookie.

The step that matters

Bake in a cool oven. A low oven temperature lets the cookies spread and dry out gradually, so they bake through without browning too quickly. Too hot an oven can scorch the outside before the centre sets.

Swap the peanut

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

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

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