Walnut Wafers

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. In a bowl, beat the eggs without separating them.

  2. Add the brown sugar, then mix in the flour and salt.

  3. Fold in the chopped walnuts.

Bake and cool

  1. Drop spoonfuls of the mixture onto buttered baking sheets.

  2. Bake until golden, then cool slightly before removing from the sheets.

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

What each ingredient does

Eggs
Bind the batter and give the wafers structure as they set in the oven.
Brown sugar
Adds sweetness, moisture and caramel flavour, and helps the wafers brown.
Flour
Provides a small amount of structure so the batter holds its shape while baking.
Chopped walnuts
Add texture and a toasted, nutty flavour throughout the wafers.

The step that matters

Bake until golden, then cool slightly. Baking until golden develops browning flavour, but the wafers are still soft when hot. Letting them cool briefly lets them firm up enough to lift cleanly from the sheets without tearing.

Swap the walnut

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

  1. Almondfits better
  2. Chestnutfits better
  3. Milletfits better
  4. Walnutthe original

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