Olive oil

Before I leave this life, I have to share a secret. Someone in my early
age taught it to me, and now I have to tell the world.
Someone taught me how to get oil from olives. Nowadays these plants are
hard to find in my hometown, but someone is still cultivating this,
trying to resist to heat.
Anyway, first of all you need trees. Take care of your olive trees,
protect them from fire, and cut away higher branches in the end of
winter: you'll get more nourishing olives. They need sun, and a bit of
water; tahe care of the soil around the trees.. And in fall, from
September to November, prepare to collect your olives. Place nets under
each tree, and take down olives. At my age peole already used air rakes,
but if you can't get them cut smaller branches and rake away olives
from them. Gather all the olives and bring them to a oil mill. If you
don't have one, make a huge bowl (out of stone, or metal) to crush
olives and dribble away oil from leftover and leaves. Elders used water
and a centrifuge, since oil floats on water: try to do is if needed.

And after all, you'll get genuine olive oil, good to preserve food, to
fry, to burn, and for many other things.
