This is Vietnamese comfort food in a bowl. If you’re looking for ways to use your watermelon rind, look no further! And if you’re asking if Watermelon Rind is even safe to eat, it absolutely is, and is especially good for you as it’s nutrient-rich in vitamins (A, C and B6). This is the prime no-waste recipe to use any rind or unsweet watermelon.

As an added bonus, I’ll even share some tricks on how to choose the perfect watermelon every time, so you can pick a juicy one, with a thin rind.

How to pick the perfect sweet & ripe watermelon

  • Colour: A uniform colour all around, with one large darker yellow spot
  • Touch: Tap on the watermelon, you want to feel a light vibration on your fingertips back. If you feel a light “bounce”, it means that the watermelon has no bruising.
  • Sugar webbings: Look for large, dried webbings, which means they’ll be sweeter.
  • Complexion: Look all around the skin to ensure that it’s smooth. This means that the rind will be thinner.
  • Weight: Feels heavy for its size.
  • Stem: Make sure that the step is dried and dark brown, and not green. This means that it’ll be ripe!
  • Preference: If you like a watery watermelon, choose an elongated one. If you like your watermelon sweet and dense, choose a uniform one.

But if you don’t get lucky, and end up with a thicker watermelon rind that’s not so sweet, this recipe would be sure to make it all tastier. So, it’s a win, win! Better luck next time.

Notes on the recipe

  • The cooked watermelon rind, resembles winter melon soup, with the soft part being the red portion of the watermelon. It makes you want to cut the watermelon in a way so that you only enjoy all the sweet parts, and leave the rest for the soup!
  • You can enjoy this with rice, or with mung bean thread noodles – or on its own (my favourite)!
  • Great watermelon rind recipe to refer to especially if you picked a watermelon that isn’t sweet!
  • Other recipes you can use with rind is Korean-style pickled watermelon rind (similar to how you would pickle radish), stir fry watermelon rind (similar to chayote), watermelon rind coleslaw, or simply juice it!
It’s hard to stop eating after you have one bite of this soup!
