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 ↓
Glace Nuts and Fruit
Ingredients
Directions
Make the syrup
Combine sugar, cream of tartar, and hot water in a granite saucepan.
Stir until the sugar dissolves.
Wipe down the sides of the pan with a cloth dampened in cold water.
Boil continuously without stirring until the syrup is brittle and clear when dropped in ice water.
Glace and set
Stand the saucepan in hot water, tilting it slightly.
Drop the nuts, grapes, and cherries into the syrup with your left hand.
Lift the fruit and nuts out immediately.
Place them on paper to harden.
Ensure the stem of the grape remains on to prevent juice from running out.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the syrup that hardens into the glossy, brittle coating.
- Cream of tartar
- Acidifies the syrup, helping prevent crystallization so it stays smooth and clear.
- Hot water
- Dissolves the sugar so the syrup can be boiled evenly.
The step that matters
Boil without stirring until brittle. Stirring during boiling can trigger sugar crystals to form, leaving the coating grainy instead of clear and glassy. The syrup must reach the brittle stage, which is confirmed by a drop in ice water, so the coating sets hard.
Swap the grape
How well each one fits the dish's main ingredients (sugar, cream, nuts):
- Vanillafits better
- Raisinfits better
- Coconutfits better
- Grapethe original
Fit is the average pairing score against sugar, cream, nuts. Candidates are from the same food group and used in at least 100 recipes.
