Name: Oat Meal Cookies
Ingredients: ½ cup butter; 1 cup brown sugar; 2 cups flour; ½ teaspoon baking soda; 2 cups rolled oats; ½ teaspoon salt; 1 cup chopped raisins; 1 teaspoon cinnamon; 2 eggs

Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Oat Meal Cookies

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Prepare

Preheat the oven to 350°F (175°C).

Make the dough

In a bowl, cream the butter and brown sugar together.
Add the eggs and mix well.
In another bowl, combine the flour, baking soda, salt, oats, raisins, and cinnamon.
Gradually add the dry ingredients to the wet mixture.

Bake

Drop small teaspoonfuls of dough onto a greased baking pan.
Bake in the preheated oven until golden.

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

What each ingredient does

Butter: Creamed with sugar to trap air and add richness and tender texture.
Brown sugar: Adds sweetness and moisture, and helps the cookies brown and stay chewy.
Eggs: Bind the dough and add structure and moisture to the cookies.
Flour: Provides the main structure that sets as the cookies bake.
Baking soda: Reacts to lift the dough and help the cookies spread and brown.
Rolled oats: Add chew and a hearty texture to the cookies.
