Why it works: Walnut and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 5,873 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Walnut Wafers

Oven, in the book's wordsA cool oven

Ingredients

Directions

The book says “a cool 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 and bake

  1. In a bowl, mix the sugar, walnut meats, flour, baking powder, salt, and eggs until well combined.

  2. Drop small spoonfuls of the mixture onto buttered baking sheets.

  3. Bake in the preheated oven until golden brown.

Serve

  1. Let cool before serving.

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 add structure as the wafers set in the oven.
Moist sugar
Adds sweetness and moisture, and helps the wafers brown.
Broken walnut meats
Provide the main flavour and texture through the wafers.
Flour
Gives a small amount of structure so the batter holds its shape.
Royal baking powder
Produces gas that lightens the batter as it bakes.

The step that matters

Drop small spoonfuls onto buttered baking sheets. The batter is loose and spreads as it bakes, so spoonfuls must be small and spaced apart. Buttered sheets keep the wafers from sticking and tearing when removed.

Swap the walnut

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

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

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