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 ↓

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.

Add the beaten eggs and salt, mixing well.
Stir in the rolled oats and Rumford's Baking Powder.
Bake
Drop spoonfuls onto a baking sheet.
Bake in a hot oven at 400°F (200°C) until brown and crisp.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and add structure as they set in the oven.
- Rolled oats
- Provide the chewy, hearty body that gives macaroons their texture.
- Butter
- Adds richness and helps the cookies brown and crisp at the edges.
- Sugar
- Sweetens the cookies and aids browning as they bake.
- Rumford's baking powder
- Releases gas to lift the dough so the macaroons rise slightly.
The step that matters
Bake in a hot oven until brown and crisp. Baking at 400°F sets the eggs and drives browning through sugar caramelization. Pulling them too early leaves them soft, while overbaking makes them dry and hard.
“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.
