Hi Tyler
Great that you have Kalamata's, wise lady your Nan. If they have started maturing it's best to let them go black before picking unless the recipe you have is specifically for half/half. You will find that they don't all start to change colour at the same time and there will most likely still be a number of green ones in the tree. If that's the case you could pick some greens and do the above recipe while waiting for the rest to mature.
I used to cut the seed pod clusters off the palms at my old address so I didn't have to pick them out the garden beds for weeks on end, these things weighed around 20kg and when they came off would sometimes change their fall angles and I had a couple of near misses as they brushed me on their way down while I was on the ladder. I started wearing a pair of brown corduroy pants when doing this work so at least some dignity could be retained.
Cheers
