Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Pecan Wafers
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, beat the eggs well.
Make and bake the batter
Add the brown sugar, flour, salt, baking powder, and chopped pecans to the eggs.
Drop the mixture by teaspoonfuls onto a baking sheet.
Bake for 6 minutes.

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
- Eggs
- Bind the batter and give the wafers their structure as they set in the oven.
- Brown sugar
- Adds sweetness and moisture, and helps the wafers brown and caramelize.
- Flour
- Provides the structure that holds the wafers together after baking.
- Baking powder
- Releases gas in the oven so the wafers rise slightly and turn light.
- Chopped pecans
- Add fat, crunch and nutty flavor to the wafers.
The step that matters
Dropping the batter by teaspoonfuls. Spacing the drops keeps the wafers from spreading into one sheet, and even portions bake evenly in the short 6-minute time. Because the wafers are thin and bake quickly, they can scorch if left in too long.
Swap the pecans
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Pecansthe original
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
