I think you are right about the olive wood that we chipped @Tyrus. I will keep shaking the bucket and it should be dry quite quickly.
As you can see from the picture above, the wood that we harvested is a relatively small haul. Just one cook's worth I reckon. I was going to throw away the leafy twigs on the right but I am wondering if they would do well on the fire once dried. I love the idea of food flavoured with a wonderful, gentle Mediterranean smell.
