Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients

Directions

The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. In a bowl, mix the sugar, sour cream, and butter until well combined.

  2. Add the baking soda and salt, then gradually incorporate enough flour to form a stiff dough.

Bake and serve

  1. Shape the dough into cookies and place them on a baking sheet.

  2. Bake in a preheated oven at 350°F (175°C) until golden.

  3. Allow to cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar
Sweetens the dough and helps the cookies brown as they bake.
Sour cream
Adds moisture and acidity to the dough, giving a soft, tender crumb.
Butter
Adds fat for richness and a tender texture.
Baking soda
Reacts with the sour cream's acidity to help the cookies rise and brown.
Flour
Provides the structure that lets the dough hold its shape as cookies.

The step that matters

Adding the flour gradually until the dough is stiff. Flour absorbs liquid and sets the cookie structure. Adding too much makes the cookies dry and dense, while too little makes them spread and turn out soft and flat.
