Step by Step Instructions
Here is a quick summary of the steps, but the detailed watermelon juice recipe can be found in the recipe card at the bottom of this post.
Step 1: Choose your watermelon. Wash it well. Cut it in half, and using a spoon, scoop out the meat.
Step 2: Add the scooped watermelon to a blender jar. You can keep the seeds since you'll be straining. Measure out homemade lemon juice or juice a lemon.
Step 3: Add lemon juice and a small pinch of sea salt to the blender jar.
Step 4: Start the blender slow, and gradually increase up to 45 seconds, then stop. Don't blend further or the blender will heat and cook the watermelon.
Step 5: Pour mixture through a fine mesh strainer and push around with a spoon to get the mixture through. Discard the pulp left behind in the strainer.
Step 6: Pour the result juice into ice-filled glasses and enjoy it right away or refrigerate to drink later.
Straining is optional. The juice will have a heavy pulp, so to create clear juice, pour it through a fine mesh strainer. You can drink the juice with the pulp however for extra fiber.
Seeds are fine. If your watermelon has seeds, include them in the mix if your blend is a high-speed blender and can pulverize them. You can eat watermelon seeds. They are rich in magnesium, zinc and fiber.
Don't over blend. A blender warms up the longer it rotates so you don't want to over blend or you'll cook the watermelon.
Foam is good. If a foam forms on the top of your watermelon water, it's fine to drink and adds an interesting texture to your drink but of course you can opt to skim it off with a spoon.
Add these options to the current recipe for a unique twist of flavor.
- Watermelon lime juice: Swap the lemon juice for lime juice.
- Strawberry watermelon juice: Add a ½ cup of frozen strawberries to the recipe for a fruity drink.
- Pineapple watermelon juice: Add ½ cup of chopped frozen pineapple instead of watermelon for a tropical twist.
- Watermelon cucumber juice: Add ½ cup chopped cucumber into the water for a greener, even more hydrating drink.
- Alcoholic additions: Add an ounce or two of gin or vodka for a grownup's version of watermelon water.
- Add flavors. Add a few mint leaves or ¼ teaspoon of mint extract to bring on a cool mint flavor. Adding a splash or ¼ teaspoon of vanilla extract gives your watermelon juice a fun hint of vanilla.
Refrigerated. Store watermelon juice in a sealed jar for up to a week in the refrigerator. If the layers separate, give it a stir, pour over ice and enjoy.
Frozen. For long term storage, freeze it in ice cube trays, then once frozen, bag the ice cubes in freezer bags and keep frozen for up to a year depending on how well sealed the package is.
Blending two cups of watermelon, and straining it, produces 1 cup of juice. This recipe produces 2 cups (16 ounces) of juice.
Yes, pour watermelon juice into ice cube trays and freeze. Bag the cubes and use them in water, or add to a glass the prior night to thaw and have fresh watermelon juice ready in the morning.
Watermelon is around 90% water and is also electrolyte-rich, including potassium, and with the addition of a pinch of salt, the drink is the perfect replenishment after a tough workout.
Drinking watermelon puree is as effective as commercial sports drinks like Gatorade in supporting the replenishment of electrolytes primarily because watermelon contains nutrients that support bio-availability of lycopene, the primary player in improving antioxidant capacity.
Watermelon pureed in a blender will contain fiber and seeds, both of which are nutritious. However, if you prefer your watermelon water or watermelon juice more clear, strain it using a fine mesh strainer.
You can strain your juice by pouring it through a layer of cheesecloth put over a bowl if you don't have a fine mesh strainer
Yes, watermelon rind carries nutrients and fiber and is edible. Be sure it was grown organically so there are no pesticides absorbed into the rind. To add it to watermelon juice, chop it small enough to be blended. Only add about ½ cup of rind to this recipe as more will add a bitter flavor.
