MIL came home with a baby watermelon the other day. Isn't she cute?
It's almost seedless (only a few white ones), with a slightly less-sweet flavor than full-sized watermelons. The skin is thinner, and the flesh doesn't taste bitter as you get near the rind.
Unfortunately, like the baby cantaloupe...I'm allergic. Damn.
Update 2/23/09: I have now found 2 other people with watermelon allergies, a co-worker's girlfriend, and my grandfather. At least I now know that I'm now insane, that people really can be allergic to watermelon.
