2. Discard the rounded end of the watermelon. Cut the watermelon into 4 even slices, each at least 1-inch thick. Remove the rind.
3. Place the slices in the roasting pan. Pour the sherry over them and dot with butter. Sprinkle with salt, and very lightly with pepper. Cover the watermelon with the parchment paper, then cover the pan tightly with foil. Roast the slices for 2 1/2 hours or until charred around the edges.
4. Place watermelon on a rimmed baking sheet to cool. Strain cooking juices. Serve watermelon with juices spooned over, and feta cheese. Adapted from 51 Lincoln
