Why it works: Chocolate and walnut are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,548 recipes. Both carry 3-ethyl-2,5-dimethylpyrazine, which smells roasted, nutty. The science ↓
Walnut Chocolate Drops
Ingredients
Directions
Make the fondant
Boil the powdered sugar and cold water for 5 minutes.
Place the mixture in a pan of cold water and beat until cool enough to form into balls.
Press a walnut into the center of each ball.
Coat and finish
Melt the chocolate in a bowl set over a boiling kettle.
Once the drops are cool, roll them in the melted chocolate using a fork.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Powdered sugar
- Forms the sweet base that sets into a firm, shapeable mixture when cooled.
- Cold water
- Dissolves the sugar so the boiled mixture can be beaten into a smooth paste.
- Chocolate
- Forms the sweet, glossy coating that hardens around each drop.
- Walnuts
- Adds crunch and a nutty flavor at the center of each drop.
The step that matters
Boil the powdered sugar and cold water for 5 minutes.. Boiling dissolves the sugar fully and concentrates the syrup, which determines whether the mixture will set firm enough to shape into balls. Boiling too little leaves it soft and sticky; boiling too long makes it hard to beat.

Fit is the average pairing score against sugar, chocolate. Candidates are from the same food group and used in at least 100 recipes.
