Fruit Gelatine

Ingredients

Directions

Make the gelatine base

  1. Soak the gelatine in 1/2 cup of cold water for a few minutes.

  2. Dissolve the soaked gelatine in 1/2 cup of hot water.

  3. Add the lemon and orange juice to the gelatine mixture.

  4. If the mixture is less than 1 pint, add more water.

  5. Sweeten to taste.

  6. Strain through a fine strainer.

Set and layer

  1. In a cool place, let it begin to set.

  2. In a mold, layer jelly, then sliced bananas or cherries, and repeat until all is used.

  3. Place in the refrigerator until firm enough to turn out.

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

What each ingredient does

Gelatine
Forms the gel that sets the liquid into a firm, sliceable jelly.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.
Orange juice
Adds fruity sweetness and aroma and contributes liquid to the jelly.
Sugar
Adds sweetness to balance the acidity of the citrus juice.

The step that matters

Dissolve the soaked gelatine in hot water. Gelatine must be fully dissolved before the juice is added, or it will set unevenly and leave lumps or grainy patches. Soaking it in cold water first lets it hydrate so it dissolves smoothly.

Swap the banana

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

  1. Limefits better
  2. Vanillafits better
  3. Blueberryfits better
  4. Bananathe original

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