The first thing to do is remove the rind from the watermelon , take out the seeds, and cut it into small cubes. Cutting the watermelon into small cubes makes it easier to blend later and obtain a smooth juice . Perfect squares aren't necessary; the important thing is that the pieces are a similar size to facilitate blending.
Next, you can either dissolve the sugar to make a syrup, or mix everything together directly. If you prefer to dissolve it, heat a cup of water . Once hot, add the sugar and stir until completely dissolved. This will create a light syrup that blends better with the juice and prevents any unmixed sugar granules. Then, remove it from the heat and set it aside.
Place the watermelon chunks in a bowl or blender . If necessary, do this in two batches so the blender can work smoothly. Add two cups of water and blend until the watermelon is completely smooth, taking advantage of the fact that watermelon is over 90% water and blends very easily. Pour in the remaining water and continue blending until you reach the desired consistency.
Once this is prepared, add the sugar dissolved in the water, which was prepared earlier, and continue mixing until you obtain a smooth juice. If the sugar hasn't dissolved, add it directly and mix until everything is well blended. Then add the lemon juice and continue mixing. The lemon provides a slight acidity that enhances the watermelon's natural sweetness and helps to better preserve its color and antioxidant nutrients, such as lycopene and beta-carotene.
Once all the ingredients are well mixed, pour the watermelon juice into a bowl and add some ice to keep it chilled . Store the remaining juice in the refrigerator to keep it cold. As you can see, preparing this refreshing drink is quick and easy. If you prefer a thinner consistency, simply add more water . The same goes for the sugar: you can adjust the amount or even substitute it with honey or agave syrup for a healthier option, although ideally you should enjoy the natural sweetness of the fruit.
Nutritional value and properties of watermelon
A moderate serving of watermelon, approximately 150 grams, provides very few calories, around 45 kcal , making it an ideal fruit for a light drink. This is because about 91% of its composition is water , so it hydrates intensely without adding much energy. The rest of its content is made up of simple carbohydrates that provide natural sweetness, small amounts of protein and fat , and some fiber that contributes to healthy digestion.
Besides being light, watermelon is rich in antioxidants such as lycopene, beta-carotene, and citrulline, as well as vitamin A and minerals like potassium and magnesium . It also stands out for its low sodium content, making it suitable for people who need to manage their blood pressure . All these compounds help protect against oxidative stress , contribute to cardiovascular health, promote proper hydration, and may reduce the risk of age-related eye problems thanks to its vitamin A, lutein, and zeaxanthin content.
How to prepare watermelon juice step by step
To prepare a smooth, refreshing, and balanced watermelon juice, you can follow a few simple guidelines that allow you to adapt the recipe to different tastes. After peeling, removing the seeds, and chopping the fruit, blend it well with cold water until you get a smooth mixture. From here, adjust the consistency of the juice by adding more or less water: less water will give you a thicker drink with more pulp; more water will result in a thinner juice, ideal for drinking in large glasses with ice.
If you want to intensify the flavor, you can chill the watermelon in the refrigerator before blending it. This will make the juice even more refreshing without needing to add as much ice, preventing it from becoming too watered down. A touch of freshly squeezed lemon not only adds freshness but also helps to highlight the fruit's sweet notes and slightly extend the drink's shelf life by slowing down oxidation.
Another important aspect is deciding whether you prefer juice with some pulp or completely strained. After blending the watermelon, you can strain the mixture through a fine sieve if you want a very smooth, pulp-free texture. On the other hand, keeping some of the pulp allows you to better utilize the small amount of fiber and achieve a more satiating feeling without increasing calories.
As for sweetening , ripe watermelon is usually sweet enough on its own and doesn't require added sugar. If the fruit isn't very sweet or you prefer a slightly sweeter drink, you can use small amounts of sugar, honey, or natural sweeteners, always in moderation. Maintaining the watermelon's natural sweetness helps ensure the juice remains a light and suitable option for a mid-morning snack, afternoon treat, or to accompany a balanced breakfast.
Watermelon juice variations and combinations with other fruits
Watermelon juice offers numerous variations , allowing it to be adapted to different times of day and personal preferences. A very popular option is to combine it with pineapple , strawberries , or apple , resulting in a mixed juice especially rich in vitamins and antioxidants. Blending two cups of watermelon with one cup of pineapple and one cup of strawberries, for example, creates a very aromatic drink with an interesting balance between sweetness and acidity.
You can also add a small amount of fresh ginger for a slightly spicy and digestive touch, or mint or spearmint leaves to the smoothie to intensify the refreshing sensation. Another option is to use some sparkling water, resulting in a watermelon juice with a fizzy texture reminiscent of a soft drink, but without the excessive added sugars and additives typical of commercial beverages.
For those seeking an extra boost of nutrients, you can add a small handful of baby spinach or kale leaves to the blender along with the watermelon and other fruits. The sweet, watery flavor of the watermelon masks the taste of the leafy greens very well, resulting in a juice that looks slightly greener but is very nutritionally complete.
Finally, another refreshing idea is to pour the watermelon juice into an ice cube tray, freeze it, and use the cubes to chill other juices or even sparkling water. This avoids ice cubes that dilute the drink and, instead, adds more flavor. Serving the juice in tall glasses with ice, accompanied by mint leaves and small pieces of watermelon or other fruit, makes for a visually appealing presentation, perfect for everyday enjoyment or informal gatherings.
Drinking watermelon juice regularly is a simple and enjoyable way to increase hydration , enjoy a very light fruit and benefit from its antioxidant compounds, all in a very easy recipe to prepare and that can be customized almost without limits.
