Ruby red and covered with fine green-tipped hairs, the rambutan is one of the most attractive Thai fruits and also one of the most delicious when eaten at the peak of ripeness between May and September when it is most plentiful. Thai rambutans are noted for their sweetness and considerable quantities are exported both fresh and canned; the main growing areas are Chanthaburi and southern provinces such as Surat Thani. 

This fruit contains 38 milligrams of vitamin C and 22 milligrams of calcium per 100 grams. A source of phosphorus, niacin, iron, protein and fiber, an average fruit contains 59 calories.
