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 beaten egg, mixing well.

  3. Sift together the baking powder, salt, and flour.

  4. Add the sifted mixture to the butter mixture.

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

Shape and bake

  1. Drop spoonfuls of the mixture onto an ungreased baking sheet, spacing them 1 inch apart.

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

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

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 trap air and give the cookies a tender, rich texture.
Sugar
Sweetens the cookies and helps them brown and crisp as they bake.
Egg
Binds the dough and adds structure and moisture to the cookies.
Baking powder
Releases gas during baking so the cookies rise and turn lighter.
Flour
Provides the structure that holds the cookies together as they set.
Peanuts
Add nutty flavor and a crunchy texture throughout the cookies.

The step that matters

Spacing the cookie dough on the baking sheet. This dough spreads as it bakes, so spoonfuls placed too close can merge into one sheet. Leaving about 1 inch between them lets each cookie set with its own edges and browning.

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.
