Orange Jelly

Ingredients

Directions

Prepare the juice and gelatin

  1. Cut a circular piece of peel one inch in diameter from the stem end of an orange.

  2. Use a spoon to remove the pulp and juice from the orange.

  3. Strain the juice from the pulp and set aside.

  4. In a bowl, soak the gelatin in cold water.

  5. Add boiling water to the soaked gelatin and stir until dissolved.

  6. Mix in the sugar, orange juice, and lemon juice.

Set and serve

  1. Fill the orange peel with the mixture and place it in a pan surrounded by ice and a little water.

  2. Ensure the orange is balanced and watch it carefully as the ice melts.

  3. Once the jelly is firm, cut lengthwise through the skin to serve.

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

What each ingredient does

Granulated gelatin
Sets the liquid into a firm, wobbly jelly as it cools.
Sugar
Adds sweetness and balances the tartness of the citrus juices.
Orange juice
Provides the main liquid and orange flavour of the jelly.
Lemon juice
Adds acidity that brightens the citrus flavour.

The step that matters

Setting the jelly over ice. The orange must be kept balanced and the ice watched as it melts, so the mixture cools evenly and sets firm without tipping or leaking before the gelatin holds its shape.

  4. Figabout as good a flavor fit

Fit is the average pairing score against gelatin, orange, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
