Karanda Jelly (Berry Jelly)

Ingredients

• 1 1/2 pounds Karanda berries (Carissa carandas) (Choose ripe fruit (pink/dark purple). Originally '1.5 lbs'.)
• 4 cups Water (Cold water. Originally '1 seer' (approx 1 quart/2 pints based on recipe context).)
• 1 1/2 cups Granulated sugar (Originally '0.75 lbs' (approx 12 oz).)

Instructions

1. 1Select ripe Karanda berries that have turned from white to pink or dark purple. Wash them thoroughly in warm water, rubbing gently to remove the sticky latex sap found on the skin. Remove the stems.
2. 2Carefully cut open the berries and remove every seed. The seeds are extremely bitter and will ruin the jelly if boiled with the fruit. Ensure not even a small piece of seed remains, while preserving as much pulp and juice as possible.
3. 3Place the pitted fruit in an enameled or stainless steel pot (avoid reactive metals like aluminum or iron unless tinned). Add the cold water. Cover and simmer over low heat.
4. 4While simmering, occasionally uncover and mash the fruit with a wooden spoon to help extract the juice. Continue cooking until the liquid has reduced slightly (to about 3 1/2 cups) and the fruit has given up its essence.
5. 5Remove from heat. Strain the mixture through a damp, coarse cloth into a clean vessel. Squeeze the cloth to extract all the juice, then discard the dry pulp and skins.
6. 6Dissolve the sugar into the strained juice. Strain the mixture once more through a damp muslin cloth into a clean preserving pan. Cook over low heat, skimming off any foam or scum that rises to the surface. Continue boiling until the liquid reduces to exactly 1 pint (2 cups) and reaches the setting point.
7. 7Immediately pour the hot jelly into a clean glass jar. If a film forms on top while cooling, remove it. Allow to cool completely until firm, then seal. The final jelly should be clear and deep red.
