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 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 the batter
Break up the walnut meat without chopping it.
Beat the eggs in a bowl.
Add the brown sugar, salt, flour, and baking powder to the eggs and mix 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.
Optionally, roll in powdered sugar before they cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnut meat
- Provides the bulk of the wafer and its nutty flavour and crunch.
- Eggs
- Bind the batter and set during baking to give the wafers their structure.
- Light brown sugar
- Adds sweetness and moisture, and helps the wafers brown in the oven.
- Flour
- Gives the batter a little body so the wafers hold their shape.
- Baking powder
- Releases gas to lighten the batter slightly as it bakes.
The step that matters
Remove from the pan as soon as they leave the oven. Sugar-rich wafers harden as they cool and stick firmly to the pan, so lifting them off while still warm prevents breaking and sticking.
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.
