It may be the end of the season, but I’ve finally figured out how to cut watermelon without chopping off my fingers. For years I’ve shied away from buying them until I finally realized to cut it as I would cut anything round (from a carrot, to a butternut squash, to a watermelon). Always start by giving yourself a flat edge. Then liberally trim off the skin. The white and light pink meat hold very little flavor. Continue by dicing small portions at a time, always rocking and rotating to give yourself a flat surface.
Is the interior of your Dutch Oven stained brown? Do you have burn spots on your stainless steel pots? Use Bar Keepers Friend, water, and elbow grease to remove. In general, try cooking with fats (oil and butter) at lower heats. If you're needing to char something, opt for a cast iron.
