And while nearly 500 varieties of avocados are grown around the world,  Americans tend to favor just a few, mostly Hass or Hass-like varieties.
But if you grew up in a tropical climate, you might prefer what are called  "green-skinned" avocados, varieties such as Simmonds or Monroe or any of the  dozens of other varieties coming from Florida.
 These avocados have a smooth skin that remains green when ripe, and they can  weigh up to 3 pounds. Green-skinned avocados also have less fat and more  moisture than Hass, giving them a milder flavor and a lighter, less unctuous  texture.
 These qualities make them well suited to sweet preparations, such as the ice  cream favored by Brazilians or milk shakes enjoyed in the Philippines.
 "Hispanics love to chop them into cubes and put them on top of a creamy  tomato soup or squash soup," says Mary Ostlund, marketing director for Brooks  Tropicals, a grower and the largest shipper of Florida avocados.
 The company promotes its avocados as "SlimCados," a "lite" fruit, with fewer  calories and less fat than avocados from California.
 To tell when avocados are ripe, give them a little squeeze. They should yield  to slight pressure, but not be mushy. Unripe avocados should be stored at room  temperature, then moved to the refrigerator when ripe. They will keep there for  two to three days.
 And while you can spend $10 on an avocado slicer, it's just as easy to run a  knife around the fruit lengthwise, then twist it slightly to separate the  halves. Remove the pit with a spoon.
 Pureed avocados hold up well in the freezer. The California Avocado  Commission recommends adding a tablespoon of lemon juice for each two pureed  avocados.
 AVOCADO FRIES
      Canola oil, for frying
1/4 cup all-purpose flour
Kosher salt
2 large eggs, beaten
1 1/4 cups panko (Japanese-style) breadcrumbs
2 firm-ripe avocados, peeled, pitted and sliced into 1/2-inch wedges
 Heat the oven to 200 degrees.
 In a medium saucepan over medium-high, heat 1 1/2 inches of oil until it  reaches 375 degrees on a deep-fry thermometer.
 Meanwhile, in a shallow bowl whisk together the flour and 1/4 teaspoon of  salt. Place the eggs in a second shallow bowl, and the panko in a third.
 One wedge at a time, dredge the avocados through the flour, shaking off any  excess, then through the egg and finally through the panko. Set the wedges aside  in a single layer.
 A quarter of the avocado wedges at a time, fry until deep golden, 30 to 60  seconds. Transfer the wedges to a plate lined with paper towels to drain.  Transfer the drained fries to an oven-safe plate and keep warm in the oven while  cooking the remaining wedges. Sprinkle with salt to taste. Serves 6.
