Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Hickory Nut Cookies
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 dough
Beat the eggs and melted butter together in a bowl.
Add the milk and sift in the cream of tartar with 1 cup of flour.
Dissolve the baking soda in a little hot water and mix it in.
Add the chopped hickory nuts and enough additional flour to form a stiff dough.
Shape and bake
Roll out the dough thinly and cut with a cookie cutter.
Bake in a preheated oven at 400°F (200°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 richness and structure as they set.
- Butter
- Adds fat for tenderness and flavor and helps the cookies brown.
- Cream of tartar
- Acidifies the dough and works with baking soda to help the cookies rise.
- Baking soda
- Reacts with the acid in the dough to produce gas that lightens the cookies.
- All-purpose flour
- Provides the structure that holds the dough together and sets during baking.
- Hickory nuts
- Add crunch and a rich, nutty aroma to the cookies.
The step that matters
Roll out the dough thinly. Thin dough bakes through and crisps evenly, while thick dough stays soft inside and may not brown well. Adding flour until the dough is stiff keeps it from spreading and makes it easier to cut clean shapes.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, egg, butter, milk, cream, flour):
- Almondfits better
- Pistachiofits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against sugar, egg, butter, milk, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
