23rd January 2019


The combination of a wet December and hot January appears to be the perfect equation for an abundant garden harvest. The fruit trees are producing fruit on steroids this summer, and six cocozelle zucchini plants are certainly keeping me on my toes.

After harvesting a(nother) basket of my favourite purple runner beans and zucchini, and pondering what to make, I received a timely request for a piccalilli-type preserve recipe to use the aforementioned vegetables. Clearly, I am not the only one experiencing a glut of this kind.

I took to the preserving pots to create a summery pickle reminiscent of my nana’s table. This delightful tart mustardy condiment is a perfect match for sharp cheese and cold meats or served alongside a vegetable quiche.

Zucchini & Purple Bean Mustard Pickle (Piccalilli)

Any selection of firm summer produce can be used, corn and capsicum would also make excellent additions. The ground fenugreek adds a savoury note to balance the brightness of the vinegar. Fenugreek can be found at bulk food stores, or substitute mild curry powder.
Prep Time 30 minutes
Cook Time 15 minutes


Per kilogram of produce:

  • 100 g salt
  • 1 litre water
  • 1 kg summer produce – I used 400g zucchini, 400g beans and 200g onions

Mustard Pickling Sauce

  • 2 cups apple cider vinegar
  • 1 cup water
  • 1/4 cup sugar
  • 2 tablespoons flour (can use tapioca or rice flour for gluten-free)
  • 1 tablespoon mustard powder
  • 1 teaspoon whole mustard seeds
  • 1 teaspoon ground fenugreek or mild curry powder
  • 1 teaspoon ground turmeric


  • First weigh the produce to determine the total salt quantity (per kilogram use 100g salt to 1 litre water). Prepare the soaking brine by combining salt and water in a bowl, stir to dissolve the salt.
  • Cut the produce into bite-sized pieces and add to the brine. Cover with a small plate to keep produce submerged, and leave to soak in the brine overnight or for at least eight hours.
  • Make the pickling sauce. Combine the vinegar, water, and sugar in a large saucepan. Bring to a gentle simmer.
  • In a jug, combine the flour and spices and add a scoop (about 1 cup) of hot vinegar mixture, stirring to make a paste. Drizzle the paste into the hot vinegar and whisk over a gentle heat until slightly thickened.
  • Fill another large saucepan with boiling water, and bring to a rapid boil. Drain and rinse the brined vegetables and add to the pan. Blanch for 2-3 minutes - the aim is to retain some crunch in the vegetables. Drain in a colander and immediately pack the hot vegetables into hot sterilised jars. Pour over the hot pickling sauce to within 2-3 mm from the top of the jar, clean the rim with a clean cloth and, secure the lids. Or heat process the jars in a water bath preserver, timing for 10-15 minutes once boiling.
  • Leave the jars to cool completely then check lids are inverted to create a vacuum seal. Store in a cool dark place and use within six months. Once opened store pickle in the fridge and consume within one month.

  1. Hi Nicola – would this work with cucumbers?! Thanks!

    1. Hi Roisin, thanks for the message. I just found it in my spam so sorry for the slow reply.
      I can’t see why cucumber wouldn’t work in place of the zucchini. Cut to the same size and briefly blanch before packing into the jars and adding the sauce. A great way to preserve cucumbers, enjoy 🙂

  2. Hi Nicola
    Is this pickle ready to use straight away once cool or does it need to ‘pickle’ for a while first?

    1. Hi Cheree, you can eat it straight away, however, as with any pickles it will improve over a few weeks.
      The leftover pickle sauce makes a lovely dressing once the jar is empty of vegetables, just add about the same quantity olive oil and shake. Enjoy!

    Hi Nicola does it thicken much as it cools mine looks too runny in the jar ? Thanks Nadine.

    1. Hi Nadine, it stays quite runny so to keep the pickles covered as you work your way through the jar. I use the leftover pickle juice (when the vegetables are all gone) to make a lively salad dressing, just add olive oil, and honey if desired and shake. Delicious!
