A pomelo or Chinese grapefruit is the largest citrus fruit and native to Southeast Asia. It is really large. Todd tried a sample at the grocery store and asked if I ever tried it. I said no, for I had no idea what it was. I remember asking someone and they told me it was a grapefruit and being not like any grapefruit I have ever seen, dismissed it. After all I lived Orange County, FL..I should know citrus, right? It is pretty delicious and not bitter like a grapefruit and can last a week!
