Did you know that you can roast watermelon? We did it this weekend. I got the idea from this amazing veg sushi post, where the author used the texture to mimic tuna sashimi. It turned out really interesting! We baked it, without any additional ingredients, for 2.5 hrs at 350 degrees. I wish I had flipped the pieces halfway through. But it was sweet and squishy, yet firm, and had a more intense watermelon flavor, and a carmelized sugar taste. It would make a great foundation for someone with cooking skills to experiment with — adding butter during the roasting process, marinating it in other flavors, etc. A fun experiment!
