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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Beat the eggs until well mixed.
Add the chopped hickory nuts, sugar, melted butter, and baking soda.
Gradually mix in the sifted flour until combined.
Shape and bake
Roll the dough thin.
Cut into shapes.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add structure and richness to the cookies.
- Hickory nut meats
- Add nutty flavor and texture to the cookies.
- Sugar
- Adds sweetness and helps the cookies brown as they bake.
- Melted butter
- Adds fat and richness, contributing tenderness and flavor.
- Baking soda
- Reacts to lift and spread the dough and aid browning.
- Flour
- Provides the structure that holds the cookies together as they bake.
The step that matters
Gradually mix in the sifted flour until combined. Adding flour gradually and mixing only until combined keeps the dough from becoming overworked, which would make the cookies tough. The dough also needs to be firm enough to roll thin and cut cleanly.
