Put sliced cucumbers and onions in a large container in this manner: a
layer of onions and cucumbers, sprinkle with part of the 1/2 cup salt and
then a layer of chopped ice. Continue to layer and end with salt and
ice. Let stand for about 3 hours or until ice has melted. Take out of
salt water and let drain a few minutes. Add spices, vinegar and sugar.
Bring to a good boil (can boil up to 10 minutes) and seal in jars.
