What is watermelon plum basil water?

Watermelon plum basil water is chilled water infused with watermelon, sliced plum, and fresh basil. The fruit gives the water a gentle sweetness and tartness, while the basil adds an aromatic, herbal note.

It is one of many ways to make melon infused water recipes without blending the fruit. The result is lightly flavored rather than as concentrated as juice.

What ingredients and ratio do you need?

For about four servings, use:

  • Water: 1,000 ml (about 4 1/4 cups)
  • Watermelon: 100 g (about 2/3 cup), rind removed and flesh cubed
  • Plum: 50 g (about 1/3 cup), pitted and sliced
  • Fresh basil: 5 g (about 1/4 cup loosely packed, or 8–12 leaves)

This ratio uses about 1 cup of chopped fruit per liter of water. The watermelon provides most of the fruit, with enough plum to add a sharper flavor. Choose a pitcher large enough to hold both the water and the ingredients comfortably.

Use ripe, firm fruit for slices and cubes that are easy to handle. The cup measurements are approximate because the size of the pieces affects how much fits in a cup.

How do you make watermelon plum basil water?

Prep time: 10 minutes
Chilling time: 2 hours
Total time: 2 hours 10 minutes
Yield: About 1 liter, or four 250-ml servings

  1. Wash the watermelon, plum, and basil under running water. Rinse the watermelon rind before cutting it, even though you will remove it.
  2. Cut the watermelon flesh into cubes. Slice the plum and discard its pit.
  3. Tear the basil leaves gently to help release their aroma.
  4. Place the watermelon, plum, and basil in a clean pitcher. Pour in the water and stir gently.
  5. Cover the pitcher and refrigerate for 2 hours. For a stronger infusion, steep for up to 4 hours.
  6. Strain out the fruit and basil, then serve the water chilled. Add ice if you like, knowing that melting ice will dilute the flavor.

Keep the fruit pieces intact rather than squeezing or blending them if you want a light infusion. Taste after the initial chilling time and leave the pitcher in the refrigerator longer if you prefer more flavor.

Why do watermelon, plum, and basil pair well?

Watermelon has a mild, juicy sweetness that gives the drink a soft base. Like other watermelon infused water recipes, this one relies on the fruit for flavor rather than turning it into juice.

Plum adds a sweet-tart contrast, especially when the skin is left on. If you enjoy that sharper fruit note, plum infused water offers another way to use it.

Basil brings a fresh herbal aroma that balances both fruits. Tearing the leaves gently releases their scent without needing a large amount; learn more about the ingredient in basil water.

The main benefit of the finished drink is hydration. Steeped infused water is very low in calories, usually under 10 kcal per glass; squeezing or eating the fruit adds the fruit’s calories. Nutrient amounts in the finished water are not the same as the amounts in the whole fruit.

Your liver and kidneys do most of your body’s detoxification, while your lungs and gut also help eliminate waste. Watermelon plum basil water supports hydration, not a special cleanse.

How should you store it?

Keep the pitcher covered and refrigerated. Strain the ingredients after 2–4 hours, and drink the infusion within 24 hours for the best flavor.

Discard any remaining water after 2–3 days, or sooner if it becomes cloudy, slimy, or sour-smelling. Do not leave it at room temperature for more than a few hours; return it to the refrigerator promptly after serving.

How can you vary watermelon plum basil water?

Make the plum flavor stronger

Use a little more plum and a little less watermelon while keeping the total fruit close to 150 g, or about 1 cup. This shifts the balance toward a more tart fruit flavor without changing the water quantity.

Make the basil flavor gentler

Use fewer basil leaves and taste after 2 hours. You can add a few more leaves and continue chilling if you want a more noticeable herbal aroma.

Keep the flavor subtle

Strain the ingredients after the first 2 hours rather than leaving them for the full 4 hours. Serve with ice for a lighter-tasting drink.

Frequently asked questions

Does watermelon plum basil water need a sweetener?

No. The fruit gives the water a gentle flavor without added sweetener. Adding sugar or another sweetener will change the drink’s calorie content.

Can I use sparkling water?

Yes, but the water may lose some carbonation while the fruit and basil steep. Keep the pitcher covered and refrigerated.

Does the plum variety matter?

Any ripe, fresh plum can work. A sweeter plum will produce a gentler flavor, while a tart plum will give the infusion more contrast.
