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 ↓
Hickory-nut Drop Cake
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.
Make the batter
Beat the egg whites to a stiff froth.
Add the rolled sugar, hickory nut meats, baking powder, and enough flour to stiffen the mixture.
Bake
Drop spoonfuls of the mixture onto a buttered baking sheet.
Bake in a 400°F (200°C) oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a stiff froth, they trap air and give the cakes their light, airy structure.
- Rolled sugar
- Sweetens the cakes and, with the whites, helps form a stable, glossy mixture that browns in the oven.
- Hickory nut meats
- Add nutty flavor and a chewy texture to the cakes.
- Baking powder
- Releases gas in the oven, helping the drops rise and lighten.
- Flour
- Added in enough quantity to stiffen the mixture so the drops hold their shape while baking.
The step that matters
Beat the egg whites to a stiff froth. Egg whites hold air only when whipped to the right stage. Under-beaten whites collapse, leaving dense cakes, while the trapped air expands in the oven to give lightness. Adding flour too early or overmixing afterward can also deflate the foam.
