SAN JUAN, P.R. -- Walking into the Casita Blanca restaurant
            is like walking into a country home, one with ceiling fans, bare
            cement floors and live poultry -- in this case a turkey named
            Gabino and a rooster known as Pancho -- roaming the indoor patio.
            In this small restaurant in the working-class neighborhood
            of Villa Palmeras, Jesús Pérez has created something
            that is simple yet rare: a place where you can experience the
            full scope of Puerto Rican cuisine, including the traditional
            dishes that are usually not found outside a home, even here on
            the island. Mr. Pérez cooks the recipes he learned from
            his mother, Aurora Ruiz, dishes like pastelón, a sweet
            plantain pie with layers of string beans and ground beef that
            is baked like lasagna, and majarete, a creamy porridge made with
            rice meal, coconut milk and cinnamon.
            "I grew up in a poor house, in a slum, but every day
            we had a banquet," Mr. Pérez said. "There was
            always an open pot simmering on the stove for anyone who wanted
            to drop in to eat."
            This is food that is complex in flavor, not spicy, never hot,
            but well seasoned, full bodied and like cooking nowhere else,
            even though the ingredients are similar to other cuisines of
            the Caribbean.
            But the true character of Puerto Rico's cooking remains largely
            a secret because it has been for the most part kept at home.
            Serious restaurants serving Puerto Rican food are scarce in the
            United States. More often, the best -- if limited -- examples
            of Puerto Rican food in American cities like New York is found
            in neighborhood fondas, lunch-counter type places like La Fonda
            Boricua on 106th Street and Third Avenue in East Harlem (under
            a sign reading Gina y George, its former name), where the food
            is served in big heaps.
            Some chefs explained this underrepresentation by noting that
            the Puerto Rican clientele are hard to please because they often
            find restaurant dishes lacking and expensive when compared with
            what is served at the family table.
            In New York, some chefs said, the nature of the Puerto Rican
            migration -- one of constant travel back and forth between Puerto
            Rico and the mainland -- makes restaurants less vital.
            "A restaurant indicates nostalgia or not being able to
            go to your country," said Alex Garcia, the executive chef
            of Calle Ocho, a pan-Latin restaurant on the Upper West Side.
            "And the reality is that even though there are many Puerto
            Ricans here, Puerto Rico is very accessible to them."
            When Puerto Ricans crave their food, they think beyond the
            tostones and fritters, the rice and beans, the roast pork shoulder
            and other staples commonly associated with their cuisine. Instead,
            one might think of a serenata, a salad of dried codfish and boiled
            root vegetables like yautía, ñame, malanga, green
            bananas and yuca, in a peppery lime vinaigrette. Or salmorejo
            de jueyes, sautéed crab meat with the intense taste of
            the island's small native crabs, which are increasingly hard
            to find as they lose their habitat to new development. Or pasteles,
            the tamale-shaped packets made up of a paste of grated plantains,
            pork, garbanzo beans, olives and raisins wrapped in plantain
            leaves.
            Mr. Garcia, who was born in Cuba but spent part of his childhood
            in Puerto Rico, found the restaurant business particularly difficult
            on the island, where he closed a restaurant after only eight
            months.
            "How do I sell an empanada for $10 if they can make it
            better or find it elsewhere for $2?" Mr. Garcia asked.
            But there are a few chefs who are taking Puerto Rican cuisine
            into high-toned restaurants. At places like Pikayo in the Condado
            tourist area of San Juan and Su Casa at the Hyatt Dorado Beach
            in Dorado, a half-hour drive east of San Juan, chefs are reinterpreting
            traditional recipes in the way so many other pan-Latin chefs
            have in recent years. They offer fusion inventions like conch
            egg roll, sautéed foie gras over candied plantains, and
            grilled veal chops served with terrine of eggplants in tamarind
            sauce.
            This new Puerto Rican cooking, called nueva cocina criolla,
            is not unlike the dishes found in Manhattan restaurants like
            Calle Ocho and Cuba Libre in Chelsea, except that it emphasizes
            Puerto Rican flavors. At Pikayo, for example, Wilo Benet, the
            chef and an owner, serves sushi tuna on arroz pegao, the crispy
            layer of rice scraped from the bottom of the cast-iron pot that
            some Puerto Ricans fight over at the end of the meal. It's a
            surprising, delicious combination.
            Like that of other Spanish-speaking Caribbean countries, Puerto
            Rican cuisine has its roots in Spain and in influences that can
            be traced to African slaves and the native Indians of the region.
            But the food is different, island to island, and one key difference
            is the mix and proportion of the herbs and spices used in stews
            and rice dishes.
            Cubans, for instance, are partial to cumin, and Dominicans
            to oregano. In Puerto Rico, the indispensable ingredients are
            cilantro and recao, a strong-smelling herb with long, spiky leaves
            found there in backyards.
            The essence of the cooking is the sofrito, a mixture of recao
            and cilantro leaves, small sweet chili peppers, onions, green
            peppers and garlic. Sautéed in corn or olive oil, it becomes
            the foundation for most dishes, like chicken with rice, red beans
            and asopao, a soupy rice stew made with chicken or shrimp.
            So vital is the sofrito in Puerto Rican kitchens that cooks
            -- using a blender to grind or, even better, mortar and pestle
            to crush the ingredients -- make it in bulk and freeze it to
            have it handy at any moment.
            "You mix those ingredients up and it's like magic,"
            Mr. Pérez said, bringing out a mortar whose aroma impregnated
            the air at his restaurant like incense.
            The other defining seasoning is adobo, a blend of salt, oregano,
            peppercorn and garlic, all crushed by mortar and pestle with
            olive oil and vinegar. So powerful is this seasoning that when
            applied to turkey it can make it taste like pork. In Puerto Rico,
            the term pavochón -- from pavo (turkey) and lechón
            (pig) -- has been coined for turkey seasoned and roasted like
            pig.
            Despite such intense flavors, Puerto Rican food is never spicy.
            (Puerto Ricans who want a stinging experience sprinkle their
            dishes with pique, a water-based hot sauce that is homemade but
            can also be bought at stores and some restaurants.) If anything,
            there is a tendency toward sweet and salty combinations that
            make heavy use of ripe plantains and sweet vegetables like pumpkin
            and sweet potato.
            Nueva cocina criolla can be traced to Alfredo Ayala, an industrial
            engineer who in 1979 decided to make a career out of his cooking
            hobby. His first restaurant, Ali Oli, opened in 1981 in a middle-class
            neighborhood in Carolina, next door to San Juan, with a menu
            rich in Puerto Rican produce and ingredients.
            Mr. Ayala, who sold Ali Oli in 1988 and is now the chef and
            owner of Su Casa, was heavily influenced by chefs in San Francisco,
            where he lived during the rage over chefs like Alice Waters and
            Jeremiah Tower and their emphasis on the French-style preparation
            of local produce.
            "They were discovering passion fruit and I'd say, I've
            eaten passion fruit since childhood!" Mr. Ayala said. 
            In Puerto Rico, Mr. Ayala turned to homegrown ingredients
            for his dishes -- things like squash, arugula, mango, pineapple
            and swordfish caught off Puerto Rico's coast. While other restaurants
            offered soup with canned asparagus or mushrooms, Mr. Ayala served
            celery root soup. He started a revolution.
            Mr. Ayala, however, dislikes the term "new cuisine."
            "What's new about it?" he said. "What it has is
            an actualization of the cuisine, but I'm not reinventing Puerto
            Rican cuisine. I'm using very basic knowledge and combining it
            with ideas from outside Puerto Rico, but I try to maintain the
            basic roots pure."
            Even old standards like mofongo, a garlicky mound of mashed
            plantains filled with chunks of pork, shellfish and other meats,
            can rise to the occasion. At Pikayo, a mofongo with shrimp is
            $28. Asked what made his mofongo worth nearly double what most
            others charge, Mr. Benet answered: "Five pieces of very
            large shrimp."
            Mr. Benet, who worked as the chef for the governor of Puerto
            Rico before opening Pikayo in 1990, heightens traditional dishes
            by using the best ingredients possible. For his version of bistec
            encebollado, an onion-smothered dish usually made with tenderized
            top round, Mr. Benet uses beef tenderloin.
            "There are things I like to invent, but I also like to
            do the classics really well," he said. "My point of
            departure is childhood -- what did your mother feed you?"
            In my case, some of the best Puerto Rican food I have had. This
            year, as a millennium gift, I gave my family a calendar filled
            with recipes I grew up with, the traditional dishes that no one
            had ever bothered to write down.
            There is arroz con pollo de Dora (my mom, Dinorah E. Pérez,
            enhances the flavor by boiling the chicken separately, then using
            the broth to cook the rice), and las costi llitas con berenjena
            de Mami Lucy, my 82-year-old aunt's country-style ribs with eggplant
            fricassee. In Mami Lucy's creation, the meat is as tender as
            the eggplant. My Titi Edda's arroz con gandules, or rice with
            pigeon peas, is so fluffy and flavorful it can be eaten by itself.
            Professional chefs bemoan the fact that many Puerto Ricans,
            my relatives included, have grown accustomed to using artificial
            flavors and seasonings as shortcuts to speed up cooking time.
            But some also note that the talent found in private kitchens
            is to blame for the scarcity of Puerto Rican restaurants.
            "It has nothing to do with the food," Mr. Ayala
            said. "It has to do with the mentality that I'd rather eat
            at home because my mom or my grandmother makes the best beans."
