Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Nut Cookies
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
In a large bowl, mix the light brown sugar and lard until well combined.
Add the beaten eggs and sour milk, mixing thoroughly.
Stir in the baking soda and chopped hickory nuts.
Gradually add flour until the dough is manageable for rolling out.
Shape and bake
Preheat the oven to 400°F (200°C).
Roll out the dough and cut into desired shapes.
Bake in the hot oven for 3 to 4 minutes until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Light brown sugar
- Adds sweetness and moisture, and helps the cookies brown.
- Lard
- Provides fat that makes the cookies tender and short.
- Eggs
- Bind the dough and add structure as the cookies set.
- Sour milk
- Adds moisture and acidity that react with the baking soda.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the dough.
- Hickory nut meats
- Add crunch and a rich, nutty aroma.
The step that matters
Baking soda with sour milk. Baking soda must be stirred in fully so it reacts evenly with the acid in the sour milk. Uneven mixing leaves pockets of bitter soda or uneven rise and browning.
