Grate the pitted courgette, peeled celery and cleaned carrots on the coarse grater. Quarter and core the peppers and slice into fine strips using a cucumber slicer. Likewise the skinned vegetable onion. Add all other ingredients and mix well.
Cover and let stand for 24 hours in a cool, dark place.
Then boil everything together. Season again to taste and cook for a maximum of 3 minutes. Then the vegetables are still firm to the bite.
Pour boiling hot into well-cleaned glasses (the vegetables should be covered with liquid) and close with boiled twist-off lids.
Turn it upside down for 5 minutes to sterilize the lid again.
This amount results in approx. 7 glasses of 400 ml each
