Jack fruit. The fruits can be enormous, up to 1 meter (3 ft) in length and weigh as much as 100 lb (45 kg). For this reason they are most often sold ready cut, in sections. The colour of the flesh varies with the variety, and can be anything from yellow to pink. In appearance the exterior may b e light green, ripening to yellow brown, and covered in hard, knobbly spines. They grow in the Western Ghats range of mountains in India.
When the fruits are immature, they provide a starchy vegetable which needs to be cooked. When ripe, they are sweet, with a strong flavour. The section should be set on a board and the thickened heart cut out. This means cutting it across ways, about half way down, below the internal stem. The flesh can then be pulled away in hunks enclosing seeds. The seeds can be peeled and cooked and have a flavour of chestnuts. The hunks of flesh which held the seeds can be stuffed with sweet fillings. In Thailand it is in season from January to May and is generally either eaten raw or fried in batter.
