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

Oven, in the book's wordsA very moderate oven

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.

Make the batter

  1. Beat the eggs very lightly, separating the whites and yolks.

  2. Stir the sugar into the yolks, then fold in the beaten whites.

  3. Add the flour, baking powder, and nuts, mixing quickly and thoroughly.

Shape and bake

  1. Drop small spoonfuls onto greased and floured pans.

  2. Place half a nut on the middle of each cookie.

  3. Bake in a moderate oven at 350°F (175°C) for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Whites trap air for lift, and yolks add richness and binding to the 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 in the oven so the cookies rise and lighten.
Nuts
Add fat, flavor and chewy texture to the cookies.

The step that matters

Mixing the flour, baking powder, and nuts. Mixing quickly keeps the whipped egg white air from collapsing, which helps the cookies rise evenly. Overmixing after the flour goes in can develop gluten and make the cookies tough.

Swap the nuts

How well each one fits the dish's main ingredients (egg, sugar, flour):

  1. Almondfits better
  2. Chestnutfits better
  3. Milletfits better
  4. 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.
