Lime

Fried green plantains. When making tostones look for unripe plantains that are a deep shade of green: The recipe will not work with ripe plantains. Ideally, the plantains should be fried the day they are purchased, but they can be kept, wrapped well in a plastic bag and chilled, for 2 to 3 days.

Can be prepared in 45 minutes or less.

Begin preparing this lovely dessert at least five hours before serving.

Gah Yan Tsui writes, via gourmet.com: "I recently enjoyed a delicious lunch at Aquavit in New York City. Marcus Samuelsson makes an incredible mussel and carrot soup. Would it be possible to acquire the recipe?" This soup tastes much better when made with fresh carrot juice. If you don't have a juicer, you can get some at your nearest natural foods store. Active time: 30 min Start to finish: 45 min

Pay de Limón At our cooking classes in Oaxaca, I guide our students through the markets, buying tastes of the thick cream (it's like milky butter with a cheesey flavor and unctuous texture), the perfumey, greenish-yellow key limes and exotic tropical fruit like guanabana, chirimoya, guava, black zapote and papaya. In order to offer more than a simple taste of these traditional foods after one trip to the market, I combined that incredible cream and lime into a simple pie for our class meal, serving it with an assortment of pureed fruits. Even with our American homemade cream (or crème fraîche) and less-tart hybrid Persian limes, the pie makes a lovely special-dinner finale.

This is one of my favorite sauces: Its deep, purpley, cranberry color is reason enough for that designation, but then again so is the bright strawberry/kiwi/watermelon flavor, with its hints of the unbridled tropics. And the fact that you can tell your guests you're serving them cactus fruit (and that it is delicious) gives you a decidedly exotic edge. The puree is very watery, like watermelon juice, so in order to give the sauce some body but not take away all the fruit's freshness, I've directed you to rapidly boil down part of the puree with sugar, then cool it and add the remaining uncooked puree. This method works well with watermelon puree, too, should you not be able to find prickly pears. You will need about 3 cups seeded, pureed watermelon pulp.

For a quick dessert, serve this tangy sauce over strawberries, purchased angel food cake or some fat-free pound cake.

Yuuan Yaki The meaty flavor of oily fish such as Spanish mackerel, pompano, or swordfish stands up nicely to this marinade. If you prefer milder-flavored fish, try cod or bass.

For this clever riff on the "frozen" Margarita, try to use natural lime pops (sold at natural and specialty foods stores) rather than artificially colored and flavored varieties.
