Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Sugar Cookies No. 4
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 bowl, mix together the sugar, egg, melted butter, melted lard, sour milk, baking soda, and vanilla extract until soft.
Shape and bake
Roll out the dough and cut into desired shapes.
Sprinkle sugar on top before baking.
Bake in a 400°F (200°C) oven until lightly golden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the dough and adds richness and structure as it sets in the oven.
- Baking soda
- Reacts with the sour milk to produce gas, helping the cookies rise and spread.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tenderness.
- Melted butter
- Adds fat for flavor and a tender crumb, and helps with browning.
- Melted lard
- Adds fat for tenderness and a soft texture in the cookies.
The step that matters
Sprinkle sugar on top before baking. Sugar on the surface caramelizes and browns in the oven, giving a crisp, golden edge. Too little sugar leaves a pale, plainer surface.
