Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Walnut Wafebs
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 the batter
Break up the walnut meat into small pieces, but do not chop.
In a bowl, beat the eggs and add the brown sugar, salt, flour, and baking powder. Mix the ingredients together thoroughly.
Fold in the walnut pieces.
Bake and serve
Drop a teaspoonful of the mixture onto a well-buttered baking pan.
Bake in a 400°F (200°C) oven until brown.
Remove from the pan as soon as they leave the oven.
If desired, roll in powdered sugar immediately after removing from the pan.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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 batter and add structure as they set during baking.
- Light brown sugar
- Adds sweetness, moisture and a caramel flavor, and helps the wafers brown.
- Walnut meat
- Adds crunchy texture and nutty flavor to the wafers.
- Flour
- Provides a small amount of structure so the wafers hold together.
- Baking powder
- Releases gas that lightens the batter slightly as it bakes.
The step that matters
Remove from the pan as soon as they leave the oven. Cookies like these firm up as they cool and stick to the pan, so they must be lifted off while still warm and pliable.
Swap the walnut
How well each one fits the dish's main ingredients (meat, egg, sugar, flour, butter):
- Almondfits better
- Walnutthe original
- Chestnutfits about as well
- Pecansfits about as well
Fit is the average pairing score against meat, egg, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
