Watermelon Plum Water: Recipe & How to Make It

Watermelon plum water is chilled water infused with watermelon and plum that takes 2 hours 10 minutes in total and makes about 1 liter (4 1/4 cups).

What is watermelon plum water?

Watermelon plum water is a fruit-infused drink made by letting cut fruit steep in cold water. The watermelon gives it a mild, fresh sweetness, while the plum adds a slightly tart, fruity note.

Unlike a smoothie or juice, the fruit is not blended or squeezed into the water. It is one of many melon infused water recipes that make plain water more flavorful without needing a sweetener.

What ingredients and ratio do you need?

For approximately 4 servings, use:

Water: 1 liter (about 4 1/4 cups), cold
Watermelon: 100 g (about 2/3 cup), diced, rind removed
Plum: 50 g (about 1/3 cup), sliced, pit removed

The recipe uses about 150 g (1 cup) of prepared fruit per liter of water. The cup measurements are approximate because the size of the pieces affects how they fit in a cup.

Choose ripe watermelon and a firm, ripe plum for the most flavor. Use a pitcher that has room for both the water and fruit, and wash the fruit before cutting it, including the watermelon rind.

How do you make watermelon plum water?

Prep time: 10 minutes. Refrigerated steep: 2 hours. Total time: 2 hours 10 minutes.

Wash the watermelon and plum under running water, then use a clean knife and cutting board to prepare them.
Cut the watermelon into small cubes, removing the rind and any seeds. Slice the plum and discard its pit.
Add the prepared fruit to a clean pitcher and pour in the cold water.
Cover the pitcher and refrigerate it for 2 hours. For a stronger fruit flavor, steep for up to 4 hours.
Serve the water cold, straining out the fruit if you prefer. Keep any remaining water refrigerated.

Cutting the fruit into smaller pieces exposes more surface area to the water. If you want a clearer drink, pour it through a clean strainer rather than pressing the fruit.

Why do watermelon and plum pair well?

Watermelon has a gentle flavor and a high water content, so it makes a light base rather than overpowering the plum. Plum brings a sharper flavor and can give the water a subtle color, depending on the fruit you use.

The two ingredients also offer different ways to adjust the taste. Use more watermelon for a softer drink, as in watermelon infused water, or increase the plum for a more pronounced fruit flavor, as in plum infused water.

The main benefit of the drink is hydration. Watermelon and plum contain nutrients, but the amount that transfers into steeped water is uncertain; eating the fruit provides more of its fiber than drinking the strained water. The liver and kidneys do most of the body’s detoxification, while the lungs and gut help eliminate waste.

How should you store watermelon plum water?

Keep watermelon plum water covered in the refrigerator and drink it within 24 hours for the best flavor. Discard it after 2 days, or sooner if it becomes cloudy, slimy or sour-smelling.

Refrigerate the pitcher promptly after preparation and return it to the fridge after serving. Use clean utensils when handling the fruit, and make a fresh batch rather than leaving cut fruit in the pitcher indefinitely.

What variations can you try?

Make it more melon-forward

Swap some of the plum for extra watermelon, keeping the total amount of prepared fruit about the same. This gives the water a milder flavor while preserving the fruit-to-water ratio.

Add a little more plum

Replace some watermelon with plum for a tarter drink. Taste after the first refrigerated steep; the flavor will depend on the ripeness and variety of the plum.

Add fresh herbs

Add a small sprig of washed mint to the pitcher for a fresh accent. Keep the herb flavor light so that the watermelon and plum remain noticeable.

Serve over ice

Pour the finished water over ice just before serving. The ice will dilute the flavor as it melts, so a longer refrigerated steep can be useful if you prefer a stronger drink.
