Put in a big bowl ....
Put 3 cups of vinegar, 3 cups sugar, 1 cup water, 1 desertsp mustard seed, 1 teasp celery seed, 1 teasp tumeric, few peppercorns, 1 teasp curry in stainless steel saucepan and bring to boil.
Pour that over the vegies and let stand for 2 hours.
Bring all to boil and put in small jars with metal lids...hot jars, seal hot.
BIG thing...don't boil for long, you want cucumber/zuch still slightly opaque and crispish, not soggy and see through.
I would do about 3 times the recipe, with huge zucchinis I often peel them, to stop it being too woody, but make sure I put in some young green ones as well for colour.
Have fun, Tracey
