Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Forms the syrup that coats the walnuts and gives sweetness.
- Cream of tartar
- Acidic ingredient that helps keep the sugar syrup from crystallising.
- Walnuts
- Main ingredient that the syrup coats.
The step that matters
Boiling the syrup. The syrup must be boiled until it changes colour, since heating sugar to the right point sets its texture and flavour. Overcooking can make it bitter, while undercooking leaves it too thin to coat the nuts well.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, cream):
- Almondfits better
- Pistachiofits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
