Why it works: Cinnamon and flour are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Oatmeal Cookies
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 the dough
Preheat the oven to 350°F (175°C).
In a large bowl, mix the milk, cinnamon, oatmeal, flour, and eggs until well combined.
Roll the dough thin and cut into shapes using a cookie cutter.
Finish and bake
Brush the cookies with beaten egg and sprinkle with sugar and a little cinnamon.
Bake in the preheated oven until golden.

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.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Oatmeal
- Provides bulk and a chewy, hearty texture in the dough.
- Flour
- Forms the structure that holds the dough together when rolled and cut.
- Eggs
- Bind the dough and add structure, and the beaten egg wash helps the surface brown.
- Milk
- Adds moisture so the dough can be mixed and rolled.
The step that matters
Roll the dough thin. Thickness controls how the cookies bake. Thin, even dough bakes through and turns crisp and golden, while thick pieces stay soft in the centre and may brown unevenly.
Swap the cinnamon
How well each one fits the dish's main ingredients (milk, flour, egg):
- Nutmegfits about as well
- Cinnamonthe original
- Jalapenofits about as well
- Turmericfits less well
Fit is the average pairing score against milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
