Glace Grapes in Nest of Spun Sugar

Ingredients

Directions

Prepare the syrup

  1. Wash the grapes and let them dry completely.

  2. In a saucepan, combine sugar and water to make a syrup.

  3. Boil the syrup until it reaches the candy stage.

  4. Remove from heat and add a few drops of lemon juice or vinegar to prevent graining.

Coat and dry

  1. Using pincers, dip each grape by the stem into the syrup, ensuring it is fully coated.

  2. Place the coated grapes on an oiled slab to dry completely.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Grapes
Provide the fruit that is coated in a hard, glassy sugar shell.
Sugar
Forms the syrup that hardens into a crisp, sweet, glossy coating as it cools.
Water
Dissolves the sugar so it can be boiled into a syrup.
Lemon juice or vinegar
Acid that helps prevent the sugar from crystallising (graining).

The step that matters

Boiling the syrup to the candy stage. The syrup must reach the candy stage so the coating sets hard and glassy when cooled. Undercooked syrup stays sticky, while overcooked syrup can turn bitter or brittle. Acid added after heating helps stop the sugar from forming grainy crystals.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (grape, sugar):

  1. Vanillafits better
  2. Applefits better
  3. Figfits better
  4. Lemonthe original

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