The pomelo tastes like a sweet, mild grapefruit (which is itself believed to be a hybrid of the pomelo and the orange[4]), 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, can be candied and sometimes dipped in chocolate or, in China, is used in stir-fry with pork.[5] 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.[citation needed]
