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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Beat the eggs together.
Add the brown sugar, salt, and flour, then mix in the walnuts.
If the mixture is not stiff enough, add a little more flour.
Bake
Drop small heaps onto well-greased parchment paper.
Bake in a 400°F (200°C) oven until brown, about 5 minutes.

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 bake.
- Brown sugar
- Adds sweetness and promotes browning and a caramel flavour.
- Shelled walnuts
- Provide the main body, texture and nutty flavour of the wafers.
- Flour
- Gives the dough enough body to hold its shape when dropped onto the paper.
The step that matters
Adding more flour only if needed. The mixture should be stiff enough to hold its shape. Too much flour makes the wafers dry and dense, while too little lets them spread thin and fragile.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, flour, egg):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Walnutthe original
Fit is the average pairing score against sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
