how to make watermelon jam

Since watermelon is naturally very watery, turning it into jam is not very straight-forward.  If you take another type of jam recipe (for example, strawberry jam, peach jam, etc.) and just change the fruit to watermelon, it won’t work :) After all, you want to end up with watermelon jam, not watermelon syrup.  My recipe produces a real thick watermelon jam that’s gorgeous red in color and tastes like extremely concentrated sweet watermelon! It’s super easy to follow and only uses 4 ingredients!

  1. I noticed that you add sugar first and then boil and add pectin. This is the reverse of what I’ve always done but would like to stay true to this recipe. Is that correct? Thank you in advance.

  2. Do you sell your jams and jelly ? I usually buy from a gal from Texas. Excellent jams but I thought if you’re local I’d buy from you..

  3. I made this, however it set super quickly. If I tried it again I would only use one packet of sure gel. I didn’t boil it the whole 20 minutes it was setting up so thick. Anymore and I could have made fruit leather with it, lol

  4. I just made this jam with the yellow watermelons we grew this year. It tastes marvelous! I used liquid pectin (certo), 3 pouches like you suggested above, and got a good product. I tried again with Sure-Jell regular, not low sugar, because I didn’t have any, and used 1 box. I didn’t cook but about 3 minutes because it seems I remember that this type will disintegrate if overcooked. Anyway, I think it will still turn out okay even if it is a soft jelly.

  5. I cut my watermelon too soon and it was not quite ripe. Would this recipe taste ok using the fruit from this watermelon? Another recipe I was looking at also suggested using pineapple with the watermelon. Any suggestions or comments?

  6. Oh my goodness, I just made 2 batch, so far ? of your watermelon jam and it turned out amazing! My hubby wanted to eat it right out of the pan. Watermelon bread is next. Ty for your recipes!!!

  7. What if i wanted to add salt to this for salted watermelon jam? I found a salted cantaloupe jam and thought I would use the same amount of salt. Any suggestions?

      Regina. I found the salted cantaloupe recipe and wondered exactly the same thing myself. That being the case, I’m making a batch of watermelon jam right now and i’m going to give that a shot and see how it turns out. If it’s anything even close to the success of the cantaloupe jam, I’m most likely gonna be hooked for life…

    I made this and it is great! It only makes 2 pints or jelly jars a batch. I could not find low sugar or no sugar pectin at my store so just used regular pectin and worked out fine. Definitely will make again; made 2 batches the first go around.

    I made my very first batch of watermelon jam using this recipe last may and i was a fan in an instant. Thanks for posting this, Melanie! I’ve now gotten a little more confident and started tweaking it just slightly but I’m staying true to the original you posted here and all credit i give goes to you. You’ve taken something I thought was impossible and made it simple enough even for a man to understand it and get it right first time out of the gate… Thank you again, so very much!!

    I have been making this jam for years, we love it.
    This year I had a hard time finding pectin. Someone said I could use corn starch. Is this true? If so how much?

    Wonderful recipe. Tastes just like jolly rancher candy. Planning on sharing this with a little neighbor boy who loves watermelon. Thanks for the recipe!
