Why it works: Brazil nut and walnut share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 66 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Christmas Fudge
Ingredients
Directions
Prepare
Grease two 9x9x2 inch pans.
Combine the first five ingredients.
Make the candy
Combine sugar with the next three ingredients in a 3-quart saucepan and heat over low heat until sugar is dissolved, stirring the mixture.
Cover the pan and bring the mixture to a boil; boil 1 minute, or until all sugar crystals on the side of the pan have melted.
Remove the cover, and if using a candy thermometer, set it in place.
Continue gentle cooking, stirring occasionally, until the mixture reaches 236°F or until a little mixture in cold water forms a softball.
Finish and set
Remove from heat and add vanilla.
With an electric mixer set at medium speed, or with a spoon, beat until the mixture is creamy and begins to hold shape.
Thoroughly mix in fruits.
Press into the pan and chill until firm enough to cut.
Nutrition, whole recipe (rough)

The flavor team
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.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Granulated sugar
- Provides sweetness and, once cooled and set, the firm body of the fudge.
- White corn syrup
- Interferes with sugar crystal formation, helping the fudge stay smooth rather than grainy.
- Light cream
- Adds fat and moisture, giving the fudge a soft, creamy texture.
- Pecan halves
- Adds fat, crunch and a toasty nutty flavor throughout the fudge.
- Walnuts
- Adds crunch and nutty flavor that contrasts with the soft fudge.
The step that matters
Cooking to 236°F or the softball test. Cooking drives off water and concentrates the sugar. Stopping at the right point sets how firm the fudge will be, so a few degrees either way changes the texture.
Swap the pineapple
How well each one fits the dish's main ingredients (brazil nut, walnut, sugar, cream, corn, syrup, vanilla):
