💬 The perfect summer drink: "Love the color. Added extra watermelon, was too lemonie." 🍉❤️
📦 Ingredients – Makes 3 Quarts
Simple & Fresh
- 🍉 6 cups pureed watermelon – about 1 medium watermelon
- 🍋 4 cups lemon juice – fresh squeezed or bottled
- 🍬 6 cups white granulated sugar
💡 Pro tip: "If you love a stronger watermelon flavor, add an extra cup of pureed watermelon. If you prefer more lemon, add an extra ½ cup of lemon juice."
📝 Step-by-Step Instructions
Step 1 – Prepare the Watermelon Puree
- Cut a medium watermelon into chunks, removing the rind and seeds.
- Puree the watermelon in a blender or food processor until smooth.
- Measure out 6 cups of puree (or more for a stronger watermelon flavor).
💡 Pro Tip
For a smoother concentrate, strain the puree through a fine-mesh sieve to remove pulp and seeds.
Step 2 – Combine and Heat
- In a large stockpot, combine the watermelon puree, lemon juice, and sugar.
- Heat over medium heat, stirring frequently, until the sugar is completely dissolved.
- Do not boil. Heat only to 190°F – this will heat up fast.
- Use a candy thermometer to monitor the temperature.
- Remove from heat as soon as it reaches 190°F.
⚠️ Important: "Do not boil the concentrate – boiling can affect the flavor and set of the concentrate."
Step 3 – Prepare Jars
- Wash quart-sized mason jars, lids, and rings in hot, soapy water.
- Sterilize jars by placing them in a boiling water bath for 10 minutes.
- Keep jars hot until ready to fill.
Step 4 – Fill and Process
- Ladle the warm concentrate into hot jars, leaving ¼ inch headspace.
- Remove air bubbles with a non-metallic utensil.
- Wipe rims clean with a damp cloth.
- Apply lids and rings, tightening to fingertip-tight.
- Process in a boiling water bath for 15 minutes (adjust for altitude).
📈 Altitude Adjustments
- 0-1,000 ft: 15 minutes
- 1,001-3,000 ft: 20 minutes
- 3,001-6,000 ft: 25 minutes
- 6,001-8,000 ft: 30 minutes
- 8,001-10,000 ft: 35 minutes
Step 5 – Cool and Store
- Remove jars from the water bath and place on a towel-lined counter.
- Let cool undisturbed for 12-24 hours.
- Check seals – lids should be concave and not flex.
- Remove rings, wipe jars, label, and store in a cool, dark place.
💡 Pro tip: "The concentrate will keep for up to 18 months in a cool, dark pantry."
🍹 How to Serve Watermelon Lemonade
Perfect Summer Drink
- 🥤 Classic Lemonade: Mix 1 part concentrate to 1 part water. Serve over ice.

💡 Pro tip: "For the best flavor, chill the concentrate before mixing – it's even more refreshing on a hot day."
💡 Pro Tips for Perfect Concentrate
- 🍉 Choose sweet watermelon: The sweetness of the watermelon affects the final flavor. Use a ripe, sweet watermelon.
- 🍋 Adjust the lemon: If you prefer a less lemony flavor, reduce the lemon juice to 3½ cups and add more watermelon.
- 🧂 Add a pinch of salt: A tiny pinch of salt can enhance the sweetness and balance the flavors.
- 🌿 Add herbs: A few sprigs of fresh mint in the jar adds a lovely herbal note.
- 🥫 Use fresh lemon juice: Freshly squeezed lemon juice gives the best flavor, but bottled works in a pinch.
