Why it works: Butter and oats are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,939 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Oatmeal Macaroons
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 400°F (200°C).
Grease your baking pan well.
Make the dough
In a bowl, cream together the sugar and butter.
Add the eggs and mix well.
Stir in the rolled oats, salt, and baking powder until combined.
Bake
Drop spoonfuls of dough onto the pan, leaving space for spreading.
Bake for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add structure as they set in the oven.
- Baking powder
- Releases gas that lifts the cookies so they rise and spread.
- Butter
- Adds fat for richness and a tender, flavorful texture.
- White sugar
- Creamed with butter, it sweetens and helps the cookies brown.
- Rolled oats
- Provide the bulk and chewy, hearty texture of the macaroons.
The step that matters
Drop spoonfuls with space between them. The dough spreads as it bakes and the baking powder lifts it. Crowded spoonfuls can bake into one merged mass and cook unevenly, so leave room between them.
“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.
