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 ↓

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.
Mix the brown sugar, walnut meats, flour, baking powder, salt, and eggs together.
Drop small spoonfuls of the mixture onto buttered baking pans.
Bake in a 400°F (200°C) oven until golden.

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.

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and help hold the wafers together as they set.
- Brown sugar
- Adds sweetness and moisture, and browns during baking for flavor and color.
- Walnuts
- Add crunchy texture and a nutty flavor to the wafers.
- Flour
- Provides a small amount of structure so the wafers hold their shape.
- Baking powder
- Releases gas in the oven to lighten the wafers slightly as they bake.
The step that matters
Bake until golden. Sugar darkens quickly once it nears the browning point, so the wafers can turn bitter if left too long. Pull them as soon as they are golden, since they keep crisping as they cool.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, meat, flour, egg):
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
- 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.
