The watermelon and raspberries are blended together and then strained to remove any seeds or pulp. The juice is then mixed with sugar and gelatin and chilled until set. The result is a light and flavorful jelly with a beautiful pink color. Watermelon-Raspberry Jelly is perfect for summer parties or as a sweet treat on a hot day.
