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 ↓
Chocolate Cookies
Ingredients
Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream together the butter and lard.
Gradually beat in the sugar.
Add the salt, cinnamon, and melted chocolate.
Mix in the beaten egg and the baking soda dissolved in milk.
Stir in the flour until combined.
Shape and bake
Roll the dough thin and cut into round shapes.
Bake in a preheated oven at 400°F (200°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, helping the cookies stay tender and flavorful.
- Lard
- Adds fat that contributes to a tender, crumbly texture.
- Sugar
- Adds sweetness and helps the cookies brown during baking.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Baking soda
- Reacts with the dough to help the cookies rise and spread.
- Flour
- Provides the main structure that holds the cookies together.
The step that matters
Roll the dough thin. Dough rolled too thick may stay soft in the middle while the edges overbake. A consistent, thin thickness helps the cookies bake evenly and turn crisp.
