Slice cukes lengthwise, remove seeds, and slice into chunks. Chop onions into chunks. Sprinkle with coarse salt and let stand overnight. Weight with heavy can on plate I usually place them in a collander inside a large bowl, so they do not sit in the liquid which drains out of them. Keeps them a bit crisper.. Next day, Drain Well. Add cut up cauliflower (cooked)

Boil sauce ingredients for 5 min. Add cukes, onions, & cauliflower and boil for approx. 1/2 hour. If too thin, stain off some sauce but keep and use as a mustard sauce. If you find it too thick (which you probably will not), add some of the water.

This is a rather forgiving recipe which may be adapted easily to your own personal taste *I personally prefer using half white sugar and half brown, or all brown, but some people prefer the colour obtained with using all white sugar.
