Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Beat the eggs until very light.
Add cold water, oatmeal, sugar creamed with butter, and baking soda. Mix until combined, then add enough flour to roll the dough thin.
Bake
Bake in a hot oven at 400°F (200°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs add structure and help bind the dough together.
- Butter
- Creamed with sugar, butter adds richness and tenderness to the cookies.
- Sugar
- Sweetens the cookies and aids browning as they bake.
- Baking soda
- Reacts with the dough to help the cookies rise and spread slightly.
- Raw oatmeal
- Provides texture and body to the cookies.
The step that matters
Rolling the dough thin. Enough flour must be added so the dough can be rolled thin without sticking. Thin dough bakes crisp and evenly, while overly wet dough spreads and bakes unevenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
