People from the south of the US pickle watermelon rinds, while Thais cook them in curry. The texture and mild flavor are perfect for absorbing spices. Next time when you have a watermelon, try watermelon rind sour curry.
I didn't think about watermelon rind being edible until a friend was talking about it. When the green skin is removed, the light green rind is still hard, but can be bitten. It's texture reminds me of cucumber or winter melon but much denser, while it's taste is simply slightly sour, perfect for cooking or pickling.
