Why it works: Nutmeg and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Cream Cookies

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the dough

In a large bowl, combine sour cream and sugar.
Add baking soda, nutmeg, and salt; mix well.
Gradually add flour until the dough is manageable.

Shape and bake

Roll out the dough on a floured surface and cut into desired shapes.
Bake in a preheated oven at 350°F (175°C) until 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

Sour cream: Adds moisture and tang, keeping the cookies soft and tender.
Sugar: Adds sweetness and helps the cookies brown during baking.
Baking soda: Reacts with the sour cream's acidity to produce gas that helps the cookies rise.
Flour: Provides structure so the dough can be rolled and cut into shapes.
