Tabbi found this fruit in a grocery store we visited with my mother on Sunday. It's called a Kiwano. or Horned Melon. She wanted to try it so we brought it home and cut it open. It has a taste kind of like cucumber, but very gelatinous. The seeds are like a cucumber, but each one is encased in a green gelatin-like, wet sack. It's not sweet, but not really sour either. Very different type of melon.
