Low-Waste Pickled Watermelon Rind

Low-Waste Pickled Watermelon Rind

By OcadoLifePublished on 18 July 2025“When you enjoy a wedge of watermelon, don’t leave the rind behind,” says Japanese American cook and food writer Kenji Morimoto, author of Ferment – a guide to making pickles and ferments. “This Low-Waste Pickled Watermelon Rind is delicious – the rind absorbs flavour while keeping its crunch. Try it with grilled fish or barbecued meats.” Allow time for overnight pickling. This recipe makes 2 (350ml) jars.

Ingredients

  • 400g (approx.) rind leftover from a watermelon, peeled and cut into thin, small slices (approx. 4cm x 1cm)
  • 200ml apple cider vinegar (check for gluten free)
  • 60g sugar
  • ½ tsp salt
  • ½ tsp chipotle chilli flakes
  • ¼ tsp coriander seeds
  • 1 thyme sprig

Method

  • Step 1

    Divide the sliced watermelon rind between 2 350ml sterilised jars. (To sterilise, wash the jars and lids; put on a tray in the oven at 180°C/ 160°C fan/gas 4 for 15 mins.)

  • Step 2

    Make the brine by adding the vinegar, sugar, salt, chilli flakes, coriander seeds, thyme sprig and 130ml water to a small-to-medium saucepan. Bring to a low simmer, then remove from the heat; set aside for 10 mins to allow the flavours to infuse and to cool a little.

  • Step 3

    Pour the still-warm brine into the jars, then pop the lid on and leave to pickle overnight, at room temperature, before transferring to the fridge. Eat within 1 month for the best texture.
