Walnut Wafers

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 the dough

  1. Chop the walnuts very fine.

  2. Beat the butter and sugar together until creamy.

  3. Add the well-beaten egg and flour, then stir in the chopped walnuts.

  4. Alternatively, add more flour and roll out the dough before cutting.

Bake

  1. Drop spoonfuls of the mixture onto buttered baking sheets and flatten slightly.

  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

Sugar
Sweetens the dough and helps it cream with butter for a light texture.
Egg
Binds the dough and adds structure as the wafers set.
English walnuts
Provide the main flavour and crisp texture in the wafers.
Flour
Gives the dough body so the wafers hold their shape.

The step that matters

Flatten the spoonfuls slightly before baking. Dough dropped as spoonfuls spreads unevenly if left high; flattening gives even thickness so the wafers bake through and brown at the same rate.

Swap the walnut

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

  1. Almondfits better
  2. Macadamia nutfits better
  3. Chestnutfits about as well
  4. Walnutthe original

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