It's funny how people can be allergic to such a wondrous, green fruit. It's delicious and sweet when ripe. The seeds, aptly arranged in an orderly fashion, is fun to bite for it requires skill. I'm not quite sure how to explain the seed part, but if you do have the habit you'll understand. (:
Allergies are cool.
P.S: Doraemon got me interested in eating tong2 luo2 shao1. It looks real tasty but it was a disappointment. Too sweet, be it real red bean paste or strawberry cream and stuff. Tried them in Japan and it wasn't as nice as it looked as well.
