I got the recipe from Green Living Australia.
- Thoroughly rinse cucumbers. Remove stems, cut off a slice from blossom ends. In large stainless steel, enamelled, or nonstick saucepan combine water, vinegar, and salt. Bring to boiling.
- Pack cucumbers loosely into hot, sterilized pint canning jars, leaving a 12 mm head space. Add 2 or 3 heads of dill or 1 tbs dill seeds and 1/2 tsp mustard seeds to each jar. Pour hot vinegar mixture over cucumbers, leaving a 12 mm head space. Wipe jar rims and adjust lids.
- Process in a boiling-water canner for 10 minutes (start timing when water returns to boil). Remove jars and cool on racks.
- Let stand one week.
