By Carla Waldemar, Contributing EditorIt's time to take your place in the vanguard and prepare for the next best-seller on the global menu. Think Greek. The recent Olympics hosted by Athens directed the spotlight onto a cuisine whose stock was already rising faster than the bechamel on a moussaka.The facts driving this food phenomenon promise it a long shelf life. For people striving to eat more healthfully, studies such as those produced by Oldways’ International Conference on the Diet of the Mediterranean show that Greeks live longer and have fewer strokes and heart attacks than many other populations. Credit goes in large part to the unique landscape of the country. Rough, rocky terrain poorly suited to all but subsistence agriculture brought the bittersweet taste of poverty, yet it also cultivated appreciation for the freshness of homegrown foods.For centuries Greece has been a hardscrabble nation, and putting food on the table meant meals of vegetables and grains, yogurt and olives, with fish if luck held out and meat as a garnish or a treat for special holidays. Today Greek cuisine is held up as the poster plate for the recommended Mediterranean diet.Mediterranean foods rode the top of the trend chart through Greece’s Adriatic neighbor, Italy. But the healthiest diet in Italy is considered by many to be that of the Puglia region in the southeast — an area so heavily influenced by Greek culture that many of the villages still retain Greek roots in their names and architecture.Greek cuisine traditions we know today go back at least a couple of millennia. While the gods on Mount Olympus were said to “party hearty” with all manner of rich food and drink, it was simple fare that their Greek subjects favored. The ingredients of these simple foods remain the cuisine cornerstone: luscious vegetables, such as eggplant, zucchini, cucumbers, garlic, onions, capers and artichokes. Favorite fruits lead off with figs, lemons, grapes and apples.Fresh herbs grow in abundance too, with oregano heading the list. Rounding out the rustic pantry are lamb (sheep being so perfectly suited to the challenging terrain), crusty breads, nuts, honey, creamy yogurt and pungent cheeses. And olives — above all, olives.The typical Greek meal strives to include as many of these flavorful ingredients at once. An array of mezedes (the small plates of appetizers Greeks were eating long before the Spaniards came up with the idea of tapas) includes a pool of tzatziki, that addictive blend of homemade yogurt, garlic — lots of it — and shredded cucumbers, to dip into with rounds of pocket bread still warm from the brick oven; melanzanasalata, a silken sea of pureed roasted eggplant (and more garlic); rings of calamari in a simple marinade; and olives. (There are always olives, served in abundance.)Next, a Greek peasant salad of Olympian proportions composed of tomatoes straight from the garden patch, freshly-sliced cucumbers, lettuce, a toss of shiny purple Kalamata olives and a crowning slab of dense, white feta cheese — all glistening with a splash of vinegar and olive oil.Surrounded on three sides by water, Greece has a fishing culture that reaches back to the Stone Age. So it’s common for the main dish to be a whole fish or some of the abundant cephalopods (squid and octopus). Even today one can spot a weathered Greek fisherman slapping an octopus on the pier — the age-old way of tenderizing. Fish are most commonly cooked quite simply on a wood-stoked grill, brushed with olive oil, sprinkled with oregano and served with a slice of lemon — nothing fussy, nothing rich — except for memories and the bones left on the plate. These are all what make up the appeal of Greek cuisine, and why it has stood the test of time.In Athens, where the Plaka’s tavernas resound with the sound of bouzouki music by the local Zorba and the thunder of crashing plates (a custom that the fiery, licorice-flavored liqueur called ouzo seems to encourage), you find waiters standing their ground at each doorway eager to lead a passer-by straight back to the kitchen, where each simmering pot is triumphantly uncovered and explained in verbiage rivaling the country’s famous poets — lamb stifado [stew] here; avgolemono (an addictive, lemony soup that is practically a national treasure) over there; a sheet pan of moussaka (waiter: ”Next door, they use [rolling eyes,] potatoes! I use eggplant!”) and crispy squares of feta-scented spanikopita (spinach and phyllo pie). Still, before it’s time for serious eating, let’s bring on those mezedes, please.
