Prickly pear of Chalki
Chalki is not one of the islands that are very green. Everywhere there are cacti big ones that have small oval shapes with their thorns on top of them. These are the known prickly pearls. Do not leave the island and tell a native to give you a taste of these unique fruit-flavors.
Handmade Macarounia of Chalki are well-known and worth trying. On the island they will serve you with fresh local butter, feta cheese and onion.
