It's Olive Season

Olives are among the easiest crops to grow: With the exception of a few treatments and an annual pruning, one simply leaves the trees to do as they will, flowering in the spring and then growing olives, which start out tiny and green, and gradually grow, darkening as they ripen. Those who harvest by hand wait until they are black, spread silk parachutes under the trees, strip the olives from the branches, and hurry off to the olive press with their crop. This if they have a grove. If they only have a tree or two, on the other hand, they cure them.

Olives cured in brine: Simple, and tasty.
Olives cured in concia: Concia is lye, and this method requires more care than the above, though it also draws more of the bitterness out of the olives.
