These are giant green olives. Green because they are picked before they ripen, this variety hails from Pugli.
The lico olive is succulent with a nutty flavour. Biting into this olive produces a sucking slurping sound. It does not have the saltiness of a brined olive, or the intense bitterness of a black greek olive.
Perfect for those who are olive shy...
I found these at the supermarket in the deli section. Good on you Foodtown.
