Watermelon Sorbet

Ingredients

• ½ small watermelon (about 960 ml cubed; 4 cups)sweet, flavourful watermelon
• 100 g (½ cup)sugar
• 60 ml (¼ cup)honey
• 2lemons or limes, juiced
• 240 ml (1 cup)fresh mint

Instructions

1. 1

   Blend watermelon

   Check that the ice cream maker’s freezer bowl is frozen, if your machine requires it. Cut the watermelon into 2.5 cm (1-inch) cubes, then blend 960 ml (4 cups) of cubes. Measure the blended fruit: you need 720 ml (3 cups), so blend more watermelon if necessary.

2. 2

   Make mint syrup

   Put the sugar, honey, lemon juice and mint in a small saucepan. Warm over medium heat until the sugar dissolves, then take the pan off the heat and leave it for 15 minutes. Strain out the mint, add the syrup to the watermelon and blend briefly to combine.

3. 3

   Chill and churn

   Refrigerate the watermelon mixture until cold to the touch, about 1 hour. Pour it into the ice cream machine and churn until it becomes difficult to churn and has the consistency of a frozen slush or Italian ice.

4. 4

   Freeze until firm

   Scrape the sorbet into a container and cover with a lid, cling film or foil. Freeze for 2–3 hours, or until hardened. A shallow container helps it firm up more quickly. Keep frozen and use within 2 months.

What is watermelon sorbet?

Sorbet is a frozen dessert made without a dairy base. This American-style version turns blended watermelon into a fruit-forward treat, with citrus and mint adding brightness.

Watermelon: A sweet, flavourful melon gives the sorbet its main taste and colour. The recipe blends the fruit before combining it with a strained mint syrup, then churns the mixture for a smooth, icy texture.

Nutrition and macros by portion

The nutrition label shows one serving as written: 92 calories, 1g protein, 24g carbs, 1g fat.

Most of the carbohydrates come from the watermelon, sugar and honey, while the fruit contributes a little protein and the recipe contains very little fat. Pair a scoop with fresh fruit or serve it after a meal with a source of protein if you want a more balanced plate.

Choose and measure the fruit

Ripe watermelon: Choose a melon that tastes sweet and full-flavoured, as its character carries through the finished sorbet. Cut it into even cubes to make blending straightforward.

Blended volume: The recipe calls for 720 ml (3 cups) of blended watermelon, not simply a set weight of whole fruit. Blend the initial 960 ml (4 cups) of cubes, check the amount, and add more fruit if needed.

Infuse the mint syrup

Dissolve gently: Warm the sugar, honey and lemon juice with the mint over medium heat until the sugar has dissolved. There is no need to boil the mixture.

Steep, then strain: Leaving the pan off the heat for 15 minutes lets the mint flavour the syrup. Strain out the leaves before blending so the sorbet has a clean texture.

Chill before churning

Cold mixture: Refrigerate the blended base for about an hour, until it feels cold to the touch. A chilled base is ready for the machine and follows the method’s stated cue.

Frozen bowl: If your ice cream maker uses a freezer bowl, make sure it is frozen before you start. Check your machine’s instructions for any specific preparation requirements.

Read the texture cues

During churning: The sorbet is ready to transfer when it looks like a frozen slush or Italian ice and becomes difficult for the machine to churn.

After freezing: Transfer it to a covered container and freeze for 2–3 hours, until hardened. A shallow container helps the sorbet firm up more quickly.

Serving and pairing

Serve it well frozen, scooping into chilled bowls if convenient. The watermelon, citrus and mint make it a natural finish to a summer meal.

For a simple contrast, serve alongside fresh berries or another piece of fruit. Let the sorbet soften briefly at room temperature if it is too firm to scoop.

Recipe notes & tips

• Taste the watermelon before blending so you know how sweet and flavourful the base is.
• Measure the blended fruit and bring it up to 720 ml (3 cups) if needed.
• Let the mint steep off the heat for the full 15 minutes before straining.
• Chill the mixture until cold to the touch before putting it in the machine.
• Use a shallow container to help the sorbet harden more quickly.

Variations

• Use lime: Swap the lemon juice for juice from the same number of limes for a sharper citrus note.
• Adjust the mint: Use a little less mint for a subtler herbal flavour.
• Stronger citrus: Choose lemons rather than limes for a familiar, bright tang.
• Serve with berries: Add fresh berries alongside each scoop for a fruity contrast.

Common mistakes to avoid

• Not enough blended fruit: Measure after blending and add more watermelon until you have 720 ml (3 cups).
• Unfrozen machine bowl: Freeze the bowl before churning if your ice cream maker requires it.
• Undissolved sugar: Keep the syrup over medium heat until the sugar has dissolved.
• Mint left in the base: Strain the syrup after its 15-minute steep to keep leaves out of the sorbet.
• Warm mixture in the machine: Chill the watermelon mixture until cold to the touch before churning.

How to store

Keep the sorbet covered in the freezer and use it within 2 months. If it becomes too firm to scoop, let it soften briefly at room temperature before serving.
