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

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

Prepare the dough

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

  2. In a bowl, cream together the sugar and butter.

  3. Add the eggs and mix well.

  4. Dissolve the baking soda in hot water and add it to the mixture.

  5. Stir in the oatmeal, flour, raisins, cinnamon, and baking powder 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.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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 add fat and tenderness to the cookies.
Eggs
Bind the dough and add structure and moisture.
Baking soda
Reacts with the mixture to help the cookies rise and spread and brown.
Flour
Provides the main structure of the cookies.
Oatmeal
Adds chewy texture and a hearty body to the dough.

The step that matters

Dissolving the baking soda in hot water. Baking soda needs to be fully dissolved so it spreads evenly through the dough; clumps can leave bitter spots and uneven rising.
