Watermelon sorbet

Ingredients

• 80 ml (⅓ cup)water
• 60 ml (¼ cup; 4 tbsp)sugar
• 350 g (2½ cups), deseeded and cut into chunkswatermelon
• 1 tbsplime juice

Instructions

1. 1

   Make the syrup

   Put the water and sugar in a small pan. Warm gently until the sugar dissolves, then take the pan off the heat and leave the syrup to cool slightly.

2. 2

   Blend the fruit

   Blend the watermelon chunks until smooth. Add the lime juice and cooled sugar syrup, then mix well.

3. 3

   Freeze the sorbet

   Pour the mixture into a container and cover it with a lid. Freeze, taking it out roughly every 1–2 hours to scrape the frozen mixture from the sides and mash it into the centre. Repeat about three times, until it has largely frozen, then leave it to freeze overnight. Alternatively, use an ice cream maker.

What is watermelon sorbet?

Sorbet is a frozen dessert made without the dairy used in ice cream. This version pairs watermelon with lime and a little sugar syrup for a bright, fruit-led finish.

The recipe is listed as Mexican cuisine, and its simple combination of watermelon and lime makes a refreshing warm-weather treat. The syrup helps sweeten and bind the mixture, while the repeated scraping breaks up icy edges.

Nutrition and macros by portion

The nutrition label shows one serving as written: 77 calories, 0g protein, 19g carbs, 0g fat.

The watermelon and sugar provide most of the carbohydrates, while the recipe contains no meaningful protein or added fat. Serve a scoop with plain yoghurt or a small handful of nuts if you would like a more substantial dessert.

Choosing the watermelon

Ripe fruit: Use sweet, juicy watermelon for the fullest flavour, and remove all the seeds before blending.

Chunk size: Cut the fruit into manageable pieces so it blends evenly into a smooth purée.

Getting the syrup right

Gentle heat: Warm the water and sugar only until the grains dissolve; there is no need to boil the syrup.

Cooling: Let it cool slightly before mixing it with the watermelon. This keeps the fruit mixture from becoming warm before it goes into the freezer.

Managing the freeze

Scrape the sides: The mixture freezes first around the edges, so scrape those icy parts into the softer centre every 1–2 hours.

Break up the ice: Mashing the frozen edges back in helps the sorbet freeze more evenly. The recipe suggests doing this about three times, then leaving it overnight to finish setting.

Checking the texture

Before the final freeze, the blended mixture should be smooth, without obvious pieces of watermelon.

Once fully frozen, the sorbet will be firm. Let it soften briefly at room temperature before scooping if it is too hard to serve.

Serving ideas

Serve the sorbet on its own as a cool dessert, or alongside fresh summer fruit. A little extra lime juice at serving time can emphasise its citrus note.

Recipe notes & tips

• Dissolve the sugar fully before taking the syrup off the heat.
• Blend the watermelon thoroughly so the mixture starts out smooth.
• Use a lidded, freezer-safe container.
• Scrape the sides regularly while the sorbet is freezing.
• Allow a firm sorbet to soften briefly before scooping.

Variations

• Extra lime: Add a little more lime juice for a sharper citrus flavour.
• Mint: Blend in a few fresh mint leaves for a cooling herbal note.
• Chilli: Add a small pinch of chilli for gentle warmth.
• Mixed melon: Replace some of the watermelon with ripe honeydew.
• Berry swirl: Fold a little berry purée through the mixture before freezing.

Common mistakes to avoid

• Boiling the syrup: Heat it gently just until the sugar dissolves.
• Leaving seeds in: Remove them before blending for a smoother mixture.
• Skipping the scraping: Work the frozen edges into the centre every 1–2 hours.
• Freezing uncovered: Cover the container with a lid as directed.
• Serving straight from a very cold freezer: Let the sorbet soften briefly so it is easier to scoop.

How to store

Keep the sorbet covered in a freezer-safe container. It is best served after the overnight freeze; let it soften briefly before scooping. The recipe does not specify a storage duration.
