Watermelon jelly, particularly made with watermelon rind, is a nostalgic treat from Southern American cuisine. Traditionally, this method of preserving fruit rinds dates back to the 19th century when resourcefulness in the kitchen was paramount. Rather than discarding the rind, cooks transformed it into a sweet and tangy jelly, often flavored with lemons and cooked to a syrupy consistency. This recipe preserves the unique texture of the watermelon rind and infuses it with citrusy brightness, making it a delightful addition to biscuits, toast, or even used as a glaze for meats. A perfect example of waste-not-want-not Southern culinary traditions, watermelon rind jelly is both eco-friendly and delicious.
