Why it works: Flour and nuts are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,180 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Hickory Nut Cookies
Ingredients
Directions
The book says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Beat the eggs very light, separating the whites and yolks.
Stir the sugar into the yolks, then fold in the beaten whites.
Add the flour, baking powder, and nuts; mix quickly and thoroughly.
Shape and bake
Drop spoonfuls onto greased and floured pans.
Place half a nut on the middle of each cookie.
Bake at 350°F (175°C) for twenty minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites beaten in add lift and an airy, light structure to the cookie dough.
- Sugar
- Sweetens the cookies and helps them brown during baking.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Baking powder
- Releases gas during baking so the cookies rise and turn tender.
- Hickory nuts
- Add rich, nutty flavor and a firm bite to the cookies.
The step that matters
Mix quickly and thoroughly after adding the flour and baking powder. Once flour is combined with liquid, gluten begins to form, so overmixing can make the cookies tough. The whipped egg whites also deflate with prolonged stirring, so the batter should be combined swiftly and evenly to keep the cookies light.
Swap the nuts
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Nutsthe 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.
