In case you were wondering if you can dry out a watermelon rind, the answer is no. I mean, you can dedicate more electricity and time to it than I did, and maybe you won’t end up with a slightly rotten, damp rind in your oven because you forgot about it for a couple of days, and maybe you won’t have to toss that disgusting mess and crank your oven to 400 to burn away that awful stench, but hey ….. For science!
