Recipe Ingredients
| Ingredient | Quantity |
| Fresh watermelon | 4 cups (juiced) |
| Granulated sugar | 2 cups |
| Lemon juice | 2 tbsp |
| Fruit pectin | 1 packet (1.75 oz) |
Ingredients Tips and Substitutes
- Watermelon: Use seedless for less prep. If using seeded watermelon, make sure to strain it thoroughly.
- Pectin: Use low-sugar or no-sugar pectin if preferred.
- Lemon juice: Adds acidity for preservation and taste. Don’t skip it.
Recipe Instructions
- Prepare the Watermelon Juice
Chop ripe watermelon into small chunks and blend until smooth. Then, strain the puree using a cheesecloth or jelly bag to collect clear, seed-free juice. - Boil with Sugar and Lemon Juice
Pour the watermelon juice into a saucepan, then add the granulated sugar and lemon juice. Mix well to combine. Stir constantly over medium-high heat until sugar dissolves completely. - Add Pectin and Boil Hard
Stir in the packet of pectin and heat the mixture until it reaches a full rolling boil. Stir vigorously and allow it to boil hard for 1 to 2 minutes. - Test for Doneness
You can use a candy thermometer (target 220°F) or do the spoon test. Place a small spoonful of jelly onto a chilled plate and let it sit for a few seconds. Then, check if it forms a gel-like consistency. - Pour into Jars and Seal
Ladle the hot jelly into sterilized mason jars. Clean the jar rims with a damp cloth, position the lids on top, and screw them on tightly to seal. - Cool and Store
Let jars cool at room temperature. Refrigerate if consuming within 2 weeks or water-bath process for long-term storage (up to 12 months).
Chef’s Tips and Variations
- Chill the jars before filling to make the process easier.
- Add herbs like mint or basil during the boil for a unique twist.
- Mix with strawberry juice for a two-fruit variation.
- Freeze leftover watermelon juice in ice trays for future use.
- Don’t skip the hard boil step; it’s essential for jelly to set.

FAQs – Watermelon Jelly Recipe
Yes, but it’s much more difficult and less reliable. Watermelon is very low in natural pectin and acid, two things essential for gelling. To make it without commercial pectin, you must:
1- Add a high-pectin acid source: Simmer the juice with a large amount of lemon juice (which also adds needed acidity).
2- Use the long-boil method: Cook the juice and sugar mixture until it reduces drastically and reaches the gel stage (220°F / 104°C on a candy thermometer). This can take a long time and risks overcooking or caramelizing the flavor.
Recommendation: For guaranteed results, use commercial pectin (like Sure-Jell or Ball brand) and follow a trusted recipe designed for low-pectin fruits.
This is a common issue. The main reasons are:
1- Incorrect Proportions: Not using enough pectin, acid (lemon juice), or sugar for the amount of watermelon juice.
2- Undercooking: Not reaching the full, rolling boil required for the time specified when using pectin, or not reaching the gel stage (220°F / 104°C) if not using pectin.
3- Overcooking Pectin: Boiling the mixture for too long before adding the pectin can break down its gelling power.
4- Old or Inactive Pectin: Using pectin past its expiration date.
5- Not Enough Natural Pectin: If not using added pectin, watermelon juice alone almost certainly won’t set.
Yes, it is a real and delicious thing! While less common than strawberry or grape, watermelon jelly is a wonderful way to capture the essence of summer. It has a light, sweet, floral flavor and a beautiful pink-amber color. It makes a fantastic gift and is excellent on biscuits, toast, or as a glaze for meats.
