In the interest of full disclosure, I really don't like mastiha. I have tried repeatedly, but I just can't figure out how to like it. It's a resinous syrup that comes from a tree that grows on the Greek island Chios, and it's sweet, piney, and unlike any other flavor. At Ergon, I tried it wrapped around a spoon and soaked in cold water (known as a submarine in Greece). Once you've sucked off all the gum, you can drink the water, which is hopefully still a little cold, and it's a refreshing way to end your meal, so mastiha fans tell me. Like many other Greek products, mastiha has a bunch of purported health benefits, and if you want to have dessert like a Greek, you shouldn't skip out on it—it's worth trying at least once.
