Fruit Glace

Ingredients

Directions

Make the syrup

  1. Make a syrup by combining water, sugar, and lemon juice in a porcelain-lined kettle.

  2. Boil for 30 minutes without stirring.

  3. Test the syrup by dropping a little into cold water; it should be hard and brittle.

Coat and set the fruit

  1. If ready, pour the syrup into a small dish and keep it liquid in a pan of boiling water.

  2. Dip fruits into the syrup, coating them thoroughly.

  3. Place the coated fruits on buttered paper or a dish to harden.

  4. For oranges, divide into sections, skewer, and ice them.

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 a brittle, glossy coating on the fruit.
Lemon juice
Adds acidity that helps keep the syrup from crystallising.
Water
Dissolves the sugar so it can be boiled into a syrup.

The step that matters

Testing the syrup before dipping. Syrup that has not boiled long enough stays soft and sticky, while overcooked syrup turns dark and bitter. The cold-water test shows whether it has reached the hard-crack stage needed for a brittle coating.

Swap the walnut

How well each one fits the dish's main ingredients (sugar, lemon, grape, banana, orange, peach):

  1. Almondfits better
  2. Pistachiofits about as well
  3. Walnutthe original
  4. Chestnutfits about as well

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