BY MARGARET GRIFFIS Tommy Atkins, Kent, Graham, Haden, and Lancetilla. Lancetilla? These aren't the names of hunky soap opera studs or zany drag queens. They're just a few of the hundreds of varieties of mangos cultivated over the last 4000 years. Sweet, fragrant, and juicy, this Southeast Asia native is one of the world's top-selling fruits. Imported to South Florida more than 100 years ago, mangos please just about everyone's palate and waistline. They're relatively low in calories and loaded with vitamins A and C, beta carotene, potassium, and fiber. So if you're going to break that low-carb diet, do it with something tempting and nutritious. The one "bad" characteristic is that a tree can produce too many mangos, so you'll have to find creative new ways to enjoy them -- before getting disgusted and leaving a pile of rotting mangos on the curb. From 10:00 a.m. to 1:00 p.m. Chris Rollins's workshop Mangos, Mangos, Mangos can provide the perfect solution. For a fee of $25 chew to your heart's content on 100-plus varieties of mangos growing at Fruit and Spice Park (24801 SW 187th Ave., Homestead). If you aren't too overstuffed, you can learn about proper care of trees, pests, disease, and pick up some new recipes. Call 305-247-5727.
