Citrus maxima - Pomelo

Dont know anything about pomelo..not sure of size but looks like a lime in colour and a grapefruit in shape..

Tetrarch:

It grows to the size of a cantaloupe. It's also the largest citrus fruit known...and ripens to very light yellow or light green.

If I recall correctly, the skin is quite thick, and it has a taste a little like watered down grapefruit?

Meanie:

Yes, the rind is very thick. The flavor is different from a watered down grapefruit. It just depends on the variety...it can be sweet or somewhat bitter and acidic.

Grapefruit are actually the result of an unplanned cross between a sour-acid pummelo and a sweet orange popular in the Caribbean at the time. On my dream list is to someday cross a sweet pummelo variety with a 'Trovita' orange, and see what results.

Tugbrethil:

That would be an interesting cross.
