🍉🍍🍈 Recipe

Ingredients:

• 4 cups seedless watermelon, cut into 1-inch cubes

• 4 cups pineapple, peeled, cored, and cubed

• 4 cups cantaloupe, peeled, seeded, and cubed

• 6 cups water

• 2 cups granulated sugar (adjust to taste)

• ½ cup lemon juice (bottled, for consistency and safety)

• Optional: 1 cinnamon stick or 2–3 whole cloves per jar for a spiced flavor

🥣 How to Make

1. Prepare jars and lids

   • Wash jars, lids, and bands in hot, soapy water.

   • Sterilize jars by boiling them in a large canning pot for 10 minutes. Keep warm until use.

2. Prepare the syrup

   • In a large saucepan, combine water, sugar, and lemon juice.

   • Bring to a gentle boil, stirring until sugar is dissolved. Reduce to a low simmer.

3. Prepare the fruit

   • Wash, peel, and cube the watermelon, pineapple, and cantaloupe.

   • Keep fruit pieces uniform in size for even canning.

4. Pack the jars

   • Carefully fill each sterilized jar with a mix of fruits (about 1 inch from the rim).

   • Pour hot syrup over the fruit, leaving ½ inch of headspace.

   • Remove air bubbles with a non-metallic spatula and wipe jar rims clean.

5. Seal and process

   • Place lids and screw bands on jars until fingertip tight.

   • Process in a boiling water bath canner for 20 minutes (adjust time for altitude if necessary).

6. Cool and store

   • Remove jars and let them rest on a towel undisturbed for 12–24 hours.

   • Check seals (the lids should not pop up when pressed).

   • Store sealed jars in a cool, dark pantry for up to 12 months.

📝 Notes

• Watermelon has a high water content, so its texture softens after canning—it’s best enjoyed chilled or added to fruit salads.

• Pineapple and cantaloupe hold their shape better and deliver a tangy-sweet balance.

• Always use bottled lemon juice to maintain acidity and ensure safe canning.

• For a lighter option, reduce sugar or try a honey syrup.

❓ FAQs

Q: Can I can just one type of fruit instead of mixing them?

Q: Do I need to refrigerate the jars after sealing?
No, once sealed properly, the jars can be stored at room temperature. Refrigerate only after opening.

Q: How long do canned fruits last?
Properly sealed jars last up to 12 months. For best flavor, consume within 6–8 months.

Q: Can I use less sugar?
Yes, sugar can be reduced, but it helps preserve texture and flavor. Do not skip lemon juice—it’s required for safe acidity.
