3 Quick Tips for Making Homemade Jelly

Here are a few quick tips to keep in mind when it comes to making your own homemade jelly recipes:

  • Stick with undamaged fruit. The fruit that you use to make your jelly should be as undamaged as possible in order to prevent it from spoiling too quickly.
  • Granulated sugar vs preserving sugar. If the jelly that you’re making will be using high-pectin fruits, then you can stick with granulated sugar. On the other hand, if you’ll be working with low-pectin fruits, it’s not a bad idea to invest in having some preserving sugar on hand as well.
  • Clean and sterilize your jars. Always use jars that have been thoroughly cleaned and sterilized when making jams and jellies. Wash them in hot, soapy water and then place them upside down to cool for 30 to 45 minutes.

How Long Will It Take for the Watermelon Jelly to Set?

Most homemade jellies will typically set properly within 3 to 4 hours.

If you’re running into any issues with your jelly setting, then it could possibly be due to one of the following reasons:

  • Using too large a volume of either sugar or fruit; stick with smaller quantities when making jelly.
  • Accidentally overcooking the jelly.

    1. Sorry Karen! I have not tried making this with a water bath. I am not 100% sure if it would be shelf stable or not without refrigeration, so I would not want to give any advice just in case, but I would love to hear from someone with a lot of experience in canning jams/jellies.

      1. Hello Emma, when are we supposed to add the rest of the watermelon? It’s only giving instructions on the first cup.

        1. Hey Michelle! Are you referring to the chunks or the watermelon juice? The recipe actually only requires 1 cup of watermelon juice, so if you have an abundance after blending the watermelon chunks I suggest either just adding some ice to a glass and drinking it like this or making a watermelon cocktail out of it :)

    1. Unfortunately that wouldn’t be possible due to the high sugar content of the watermelon itself. You may be able to make the jelly without adding sugar, but the texture would be much different and probably a lot more runny.
