Watermelon Jam Recipe

Watermelon jam is one of those recipes that starts as curiosity and quickly turns into something you want to keep around all summer. It’s lighter and fresher than most jams, with a soft sweetness that actually tastes like watermelon instead of just sugar. I usually make this when I’ve got extra watermelon that’s too much to eat on its own but too good to waste.

The first time I made watermelon jam, I didn’t expect much from it. Watermelon feels so delicate and watery that it doesn’t seem like a natural candidate for jam. But with slow cooking and a little citrus, it transforms into something smooth, bright, and surprisingly versatile. This version came after learning to be patient with the simmer and not rush the thickening.

Recipe Origin or Trivia

Watermelon preserves have been made in various cultures, especially in regions where watermelon grows abundantly. While watermelon rind is often preserved, fruit-based watermelon jams gained popularity as a way to reduce waste and capture summer flavor in a spreadable form.
