Combine sliced cucumbers, onions and salt in a large bowl, add enough cold water to cover. Let sit for a couple hours.
After the cucumbers and onions have sat in the salt water for a couple hours...Place all the brine ingredients in a large pot. Bring to a boil.
Meanwhile rinse the salt off of the cucumber mixture.
Add the rinsed cucumber mixture to the brine and return to boil.
Once heated through you can either cool and store in the fridge until devoured OR waterbath for long term storage. These taste better the longer they sit, so give the flavors time to marry up before serving.
