Why it works: Pecans and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Mexican Sugar Candy
Ingredients
Directions
Make the candy
Heat 1 cup of sugar in an iron saucepan until it melts, being careful not to let it burn.
Remove from heat and let it cool slightly.
Add the milk and the remaining ½ cup of sugar, stirring to combine.
Cook the mixture until it reaches the soft ball stage.
Remove from heat and add the pecans.
Stir until the mixture granulates.
Set and serve
Pour into a greased shallow pan.
Flatten the mixture quickly.
Let it cool before breaking into squares.

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: 2,3-butanedione (butter, sweet).
Sugar and milk barely smell alike, yet cooks put them together in 77,875 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
- Pecans
- Add texture and a toasty, nutty flavor that contrasts with the sweet candy base.
- Milk
- Adds moisture and creaminess, and its proteins and sugars help give the candy a soft, smooth body.
- Granulated sugar
- Provides sweetness and, once melted and cooked, forms the crystalline structure of the candy.
The step that matters
Stir until the mixture granulates. Stirring a cooked sugar mixture controls crystal formation. Stir too little and the candy stays glassy or soft; stir too long after it has begun to set and it hardens before it can be poured and flattened.
Swap the pecans
How well each one fits the dish's main ingredients (sugar, milk):
- Cocoafits better
- Almondfits better
- Chestnutfits better
- Pecansthe original
Fit is the average pairing score against sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
