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.

Make the dough

  1. Beat the butter and sugar together until creamy.

  2. Gradually add the egg and mix well.

  3. Combine the dry ingredients and mix them in carefully.

Bake

  1. Place small heaps of the mixture on a greased baking sheet using a teaspoon.

  2. Bake in a moderate oven at 350°F (175°C) for about 15 minutes.

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 a tender, rich crumb.
Flour
Forms the main structure of the nuts as it sets in the oven.
Cornflour
Lightens the texture, making the biscuits more tender and crumbly than flour alone.
Baking powder
Releases gas in the oven, helping the nuts rise and become light.
Egg
Binds the mixture and adds moisture and structure.
Sugar
Sweetens the dough and helps it brown during baking.

The step that matters

Creaming the butter and sugar. Beating until creamy traps air in the fat, which helps the nuts stay light. Under-beaten butter gives dense, heavy results.
