Ojen fruit

From The Stargate Omnipedia


Fruit known to grow on Arkhan's planet, with a grayish skin and white flesh. Its skin is tart and should be peeled before eating. The taste is said to be a cross between a guava and a mango, leading Daniel Jackson drolly to suggest that it should instead be called a "guango." King Arkhan the First made it so.


It's Good To Be King - King Arkhan introduces SG-1 to Ojen fruit, and with their advice, soon changes its name to "guango."
