Banana Jelly

Ingredients

Directions

Make the jelly

  1. Combine the lemon peel, lemon pulp, gelatin, sugar, and water in a glazed or enamelled pan.

  2. Boil the mixture gently without a lid until it reduces to less than 1 pint, skimming off any scum.

  3. Remove from heat and skim the jelly as it clears.

  4. Add the sliced bananas to the jelly and mix well.

  5. Let the mixture stand for 10 minutes.

Set and serve

  1. Pour the mixture into a wetted mold.

  2. Refrigerate or place on ice to set for about 6 hours.

  3. Turn out the jelly and serve with whipped cream.

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

What each ingredient does

Gelatin
Sets the liquid into a firm, sliceable jelly as it cools.
Sugar
Adds sweetness and helps balance the sharpness of the lemon.
Lemon pulp
Adds acidity and bright lemon flavour to the jelly.
Ripe bananas
Add sweet banana flavour and soft fruit pieces to the set jelly.
Whipped cream
Adds richness and a light, cool contrast to the tart jelly.

The step that matters

Boil the mixture gently without a lid. Gentle boiling reduces the liquid and concentrates flavour without a hard boil that could cloud the jelly. Skimming removes scum so the set jelly looks clear.

Swap the lemon

How well each one fits the dish's main ingredients (gelatin, sugar, banana, cream):

  1. Vanillafits better
  2. Strawberryfits better
  3. Pineapplefits better
  4. Lemonthe original

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