Why it works: Peanut and nuts share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 81 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Boston 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
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugars.
Add the beaten egg and mix well.
In another bowl, combine the flour, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture.
Stir in the hot water, milk, peanuts, cinnamon, chopped nuts, lemon juice, and raisins.
Bake
Drop spoonfuls of the mixture onto a baking sheet.
Bake for 10-12 minutes or 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.

Shared aroma: guaiacol (smoky, sweet).
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
- Adds fat that makes the cookies tender and rich.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Beaten egg
- Binds the dough and adds structure and moisture.
- Sugar
- Sweetens the cookies and helps them brown.
- Baking soda
- Reacts with acid in the dough to help the cookies rise and spread.
- Baking powder
- Releases gas during baking to give the cookies lift.
The step that matters
Gradually add the dry ingredients to the wet mixture.. Adding flour in portions and stirring gently keeps the dough smooth and prevents overworking, which would make the cookies tough.
Swap the nuts
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk, peanut, cinnamon):
- Almondfits better
- Cashew nutfits better
- Flaxseedfits better
- Nutsthe original
Fit is the average pairing score against butter, sugar, egg, flour, milk, peanut, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
“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.
