Oatmeal Cookies

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 ↓

Oatmeal 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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the dough

  1. In a large bowl, cream together the butter and sugar.

  2. Add the eggs and sour milk, mixing well.

  3. Stir in the baking soda and salt.

  4. Gradually add the flour, oatmeal, raisins, and nuts, mixing until combined.

Bake

  1. Drop spoonfuls of the dough onto a baking sheet.

  2. Bake for 10-12 minutes or until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Butter
Creams with sugar to trap air and add richness and tenderness to the cookies.
Sugar
Sweetens the dough and helps create a crisp, golden browned edge.
Eggs
Bind the dough and add structure and moisture as the cookies set.
Sour milk
Adds moisture and acidity that reacts with the baking soda to lift the dough.
Baking soda
Reacts with the acidic sour milk to release gas, helping the cookies rise and spread.
Flour
Provides the structure that holds the cookies together as they bake.

The step that matters

Adding the baking soda to the sour milk mixture. Baking soda needs an acid to react and release gas. Stirring it in promptly after the sour milk is added lets the reaction lift the dough before baking sets it.

Swap the nuts

How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour, raisin):

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

Fit is the average pairing score against butter, sugar, egg, milk, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
