Watermelon Rind Jam (Candied Watermelon Rind)

What to do with watermelon rind or peel? Aromatic and sweet watermelon rind jam or candied watermelon rind.

Watermelon Rind Preserves

After making Homemade Blueberry Sauce, Low-Sugar Apricots in Jars, Simple Apricot Jam, Homemade Creme de Cassis, and Candied Cherries, I finally got to making some delicious watermelon rind jam or candied watermelon rind in syrup.

OK, I am sure you will not make watermelon rind jam out of all the watermelons you get to eat in the summer, but taking the time to do this at least once or twice, it’s really worth it.

You will love these sweet, jewel-like pieces of watermelon rind, you will probably not be able to eat half a jar in one go, but you will be delighted with a moderate amount of it on your toast or just being able to pop a small piece of candied watermelon rind in your mouth whenever you crave something sweet.

One piece of candied watermelon rind and you will forget about chocolate, gummy bears, or candy or whatever sweets you normally cannot resist. At least it works for me, but I was never much into chocolate, gummy bears or candy… 🙂

And try some regular watermelon jam as well, the sort that is using the pulp of the fruit.

How to make watermelon rind jam?

Well, the process is easy but it involves a few steps and a bit of chopping. But like I’ve said it before, it is well worth it!

The result will be a jam the likes of you probably never had before, unless you’re Romanian and grew up on a thing called “dulceata”, which is some kind of jam, but quite different from the regular jam you are used to. I think you will love those rather firm watermelon rind pieces surrounded by that sweet and heavy syrup.

Dulceata or “sweetness” is a kind of preserve made with whole fruits (in this case the chopped watermelon rind) boiled in a lot of sugar, normally on a 1:1 ratio, until the liquid becomes a clear syrup surrounding those glossy fruit or fruit pieces.

As dulceata is way sweeter than regular jam, you will only need a small amount of it on your buttered toast, for instance. And the fruit can be used not only to eat as it is, but you can also put it into cakes, stir it into desserts and so on.

Steps:

  • Remove the green skin of the watermelon completely.
  • Make sure to leave a tiny amount of red watermelon flesh attached to the rind pieces you want to use for the jam. It makes things prettier, however, you don’t want to leave too much of it attached, I would say about 2 mm/ 0.08 inches.
  • Chop the rind as evenly as possible, about 3-4 cm/ 1.2-1.6 inches.
  • You should weigh the watermelon rind now and prepare more if necessary, you will need roughly 750 – 850 g/ 1.7 – 1.9 lbs, weighed after preparing the rind. If you don’t have enough, prepare some more.
  • Cook the watermelon rind pieces in water and vinegar, this step takes about an hour, but it is a necessary step. The vinegar will help the watermelon rind pieces hold their shape and not get soggy.
  • After cooking the watermelon rind in vinegar, let drain well. When cool enough to handle, press with your hand to remove more of the excess water.
  • Weigh the drained and pressed watermelon pieces. You will need exactly the same amount of sugar as the rind weighs, so 1 to 1 ratio. You will have more or less 500 g/ 1.1 lbs of watermelon rind pieces.
  • Place the sugar in the rinsed pot you used before.
  • Add 250 ml/ 8.5 fl. oz/ 1 cup water to the sugar and turn on the heat. Stir to dissolve the sugar. When the syrup comes to a boil, add the watermelon rind and the lemon juice.
  • Cook until a light syrup forms, it took me exactly 38 minutes.
  • Place the watermelon rind jam into the sterilized jars and seal well.
  • Keep in a dark cool place. If the jars are sterilized and well-sealed the jam should be good for a very long time.

For more info on sterilizing jars, have a look at this post explaining how to sterilize jars.

How long to cook the jam?

  • The most difficult thing for me when making dulceata is finding the perfect time to stop the cooking process. If the jam is cooked too shortly, the syrup will not form properly and the jam will be runny.
  • If you overcook the jam, the syrup will taste too much like caramel and become too hard, I had to throw away a whole batch of cherry dulceata because I was not even able to stick a spoon in the finished and cooled product…
  • *However, to make it easier for you, I measured the cooking time exactly, and considering you will follow the instructions and use a pot that has roughly the same size as mine, you should be able to stop the cooking process at the right time.
  • I used a soup pot with a diameter of 23 cm/ 9 inches and a height of 14 cm/ 5.5 inches. Of course, I don’t expect you to have the exact same pot or to buy one extra for this, but a similar sized one will help you with keeping the indicated cooking time better.
  • If your pot is wider, start checking if the syrup is formed before the indicated time is over, if your pot is narrower it might take a bit longer.
  • The syrup should have more or less the consistency of runny clear honey.

The source of this recipe is Silvia Jurcovan’s Cookbook. I only made half a batch and got 2 ½ small jars.

And what to do with this candied watermelon rind or watermelon rind jam? Except for eating it as it is? Why not try putting some in a fruitcake, either a regular boozy fruitcake or a non-alcoholic fruitcake.

Watermelon Rind Jam (Candied Watermelon Rind)

Yield: 2-3 small jars
Prep Time: 20 minutes
Cook Time: 1 hour 50 minutes
Total Time: 2 hours 10 minutes

What to do with watermelon rind or peel? Aromatic and sweet watermelon rind jam or candied watermelon rind.

Ingredients

  • 750 – 850 g/ 1.7 – 1.9 lbs watermelon rind, weighed after preparing it
  • granulated sugar, about 500 g/ 1.1 lbs (depending on how much cooked rind you have)
  • 1 liter/ 34 fl.oz/ 4.2 cups water
  • 150 ml/ 5 fl.oz/ 2/3 cup white wine vinegar
  • the juice of 1 lemon

Instructions

  1. Remove the red flesh of the watermelon, leaving only one very thin layer of red flesh attached to the rind, about 2 mm/ 0.08 inches. Remove the green skin of the watermelon completely.
  2. Chop the watermelon rind into even pieces of about 3-4 cm/ 1.2-1.6 inches. You should weigh the watermelon rind now and prepare more if necessary.
  3. Place 1 liter/ 34 oz/ 4.2 cups water and the vinegar in a pot with a diameter of approximately 23 cm/ 9 inches and a height of 14 cm/ 5.5 inches (*See the marked paragraph above).
  4. Bring to a boil, add the watermelon rind and let cook for about an hour or a bit more until the rind pieces are glossy and somehow transparent. It is a necessary step, the vinegar will help the watermelon rind pieces hold their shape and not get soggy.
  5. Drain in a sieve, refresh with cold water and, when cool enough to handle, press with your hand to remove more of the excess water.
  6. Weigh the watermelon rind again. You should have more or less 500 g/ 1.1 lbs cooked rind. Set aside.
  7. Measure the sugar, you should use the same amount of sugar as you have of cooked watermelon rind, so about 500 g/ 1.1 lbs.
  8. Place the sugar in the rinsed pot you used before. Add 250 ml/ 8.5 oz/ 1 cup water to the sugar and turn on the heat. Stir to dissolve the sugar. When the syrup comes to a boil, add the watermelon rind and the lemon juice.
  9. Cook until a light syrup forms, it took me exactly 38 minutes, but as I have mentioned above, the cooking time depends on the size of the pot as well. I used a soup pot with a diameter of 23 cm/ 9 inches and a height of 14 cm/ 5.5 inches.
  10. If your pot has a similar size the time should be OK, if your pot is wider the cooking time will probably be shorter, if your pot is narrower the cooking time will probably be a bit longer. The finished syrup should be light in color and have more or less the consistency of clear honey.
  11. Place the jam into the sterilized jars and seal well. Keep in a dark cool place. If the jars are sterilized and well-sealed the jam should be good for a very long time.

IS this supposed to be covered during the cooking times? Mine cooked out of liquid before the times were up, like 1st cook was well below an hour.

Hi Peg. I didn't cover the pot. You could do it, leaving a crack open while you cook the rind in vinegar, if you feel it boils down too quickly. Or turn the heat down a bit. You should definitely NOT use a lid while you cook the jam.

I modified it slightly by adding new ginger and orange zest. Delicious. I will also try it with finely diced beetroot. I also used citric acid and tartaric acid instead of lemon juice.

Hi! I was wondering, I never canned anything before. Does this have to be canned? Or can I just use a empty cleaned pasta jar I have in the cabinet?

Hi Jisela. You don 't have to can this. Give the jam into sterilized jars. There is a link in the blog post that will lead you to another post where I explain how to sterilize jars.
