The pomelo (Citrus maxima or Citrus grandis) is a crisp citrus fruit native to South and Southeast Asia. It is usually pale green to yellow when ripe, with sweet white (or, more rarely, pink or red) flesh and very thick albedo (rind pith). It is the largest citrus fruit, 15-25 cm in diameter and usually weighing 1-2 kg.
The pomelo is native to Southeast Asia and is known there under a wide variety of names. In large parts of Southeast Asia, it's a popular desert, often eaten raw sprinkled with or dipped in salt mixture. It is also eaten in salads or together with yogurt, and sometimes pickled.
The pomelo tastes like a sweet, mild grapefruit (which is itself a hybrid of the pomelo and the orange), though the typical pomelo is much larger in size than the grapefruit. It has very little, or none, of the common grapefruit's bitterness, but the enveloping membranous material around the segments is bitter, considered inedible, and thus usually is discarded. The peel is sometimes used to make marmalade, or is candied and sometimes dipped in chocolate.
Pomelos are usually grafted onto other citrus rootstocks, but can be grown from seed, provided the seeds are not allowed to dry out before planting. The seedlings take about eight years to start blooming and yielding fruit.
