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 the butter and sugar together.

  2. Add the beaten egg, lemon juice, and milk.

  3. Mix and sift the flour and baking powder, then stir in the chopped peanuts.

  4. The mixture should be a stiff drop batter.

Bake

  1. Drop by teaspoonfuls onto buttered pans, spacing them 1-2 inches apart.

  2. Bake in a 400°F (200°C) oven for 5-10 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Butter
Adds fat and richness, helping the cookies stay tender and carry flavor.
Sugar
Creamed with butter to add sweetness and help the cookies brown.
Egg
Binds the batter and gives the cookies structure as they set.
Flour
Provides the main structure that holds the cookies together as they bake.
Baking powder
Releases gas during baking so the cookies rise and lighten.
Finely chopped peanuts
Add nutty flavor and a bit of texture throughout the cookies.

The step that matters

Keep the batter stiff. A stiff batter holds its shape when dropped, so the cookies spread only a little and keep a domed form. A batter that is too loose spreads thin in the oven and can become flat and crisp.

Swap the peanut

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

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

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