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
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
Preheat the oven to 350°F (175°C).
Mix and bake
In a bowl, mix together the brown sugar, chopped walnuts, beaten egg, flour, and baking powder.
Drop small spoonfuls of the mixture onto well-buttered baking pans.
Bake in the preheated 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.

Egg and flour 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
- Brown sugar
- Adds sweetness and moisture, and helps the wafers brown as they bake.
- Walnuts
- Add texture and a nutty flavor to the wafers.
- Egg
- Binds the mixture together so the spoonfuls hold their shape.
- All-purpose flour
- Provides structure so the wafers set rather than spread into a loose mass.
- Baking powder
- Releases gas in the oven, lightening the batter slightly as it bakes.
The step that matters
Bake in the preheated oven until golden.. Golden color signals that the sugar and flour have browned and the wafers are cooked through. Underbaked wafers stay soft and sticky, while overbaked ones turn bitter and brittle. Wafers firm up further as they cool.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, meat, egg, flour):
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
- Pistachiofits about as well
Fit is the average pairing score against sugar, meat, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
