Quick update

It's now been 4 weeks and the olives are still turning the water dark red.



Will they be edible? Keep checking back to find out.

Doctor, doctor! Can you cure my olive?

We went for a hike about a couple of weeks ago with some friends through a forest in the mountains just off the road from Marbella to the town of Coin. The weather was fantastic which after the rain fall Spain and in fact the rest of the Iberian peninsular has sufferred recently was very welcome. The walk was very relaxing and led to a viewing point on the edge of a cliff with most of the Costa Del Sol spread out before us. From this point Marbella lay in front of us with views of the coast up to Malaga in one direction while in the other direction we could just make out the shape of Gibraltar in the distance. From this point it is also possible, on a clear day of course to see the coast of Africa just across the Med'. During the walk back to where we had parked our cars we passed through some olive groves and while most of the trees were bare, my daughter noticed a few which still had some olives on the branches. Being quite fond of olives we decided to pick a few but were warned by our companions not to eat them straight from the tree as they are far too bitter. Aparently, olives need to be cured first and hence the title of this post.

How do you cure olives? well after a bit of research, it appears that one way is to soak them in brine (water with a high consentration of salt) for about six weeks before trying them. Now I love experimenting with things; always have. I'm still amazed that the family home was not burned to the ground with some of the wilder experiments I attempted with my chemistry set as a young teenager. By comparison, curing olives is safe and non-incendary.

The photo that follows shows a small test group of olives which have been in salt water for a week now. The water has to be changed weekly and in fact was done just prior to the photograph being taken. Water from the first week had actually turned a dark red colour.

The idea is that after the six weeks, I will cook an Italian feast with the olives being a part of the ingredients. Look out for that blog next month. In the meantime you can find a weekly update on the olives right here.
