This post has gone quiet with replies..and with reason..
Olive are lot of work to process so that they are 'edible'. I once looked into this...and found it soo troublesome process to be worth of efford for sake of few olives.. ::)
If my memory serve me right..it involved lot of soaking, fermenting and rinsing.
But....WELL DONE you..getting your own olives!.. ;)
Perhaps little googling would be in place for finding the right treatment for them..
I'll have a look too if I still find the info..
