Creating the Base for Watermelon Foam

To craft a refreshing watermelon foam perfect for summer dishes, you’ll need to select the right ingredients, prepare a watermelon puree, and add suitable sweeteners and flavour enhancers. Using FastGas whipped cream chargers will help create a light and frothy texture, uniquely enhancing your culinary creations.

Selecting Ingredients

  • Seedless watermelon: Opt for a ripe, juicy, and seedless watermelon to ensure a smooth puree.
  • Sweeteners: Consider white sugar or granulated sugar for a neutral sweetness.
  • Acidity and Seasoning: Freshly squeezed lemon juice adds a zesty brightness, while a pinch of salt can enhance the overall flavour profile.
  • Oil: A drizzle of a subtle oil, like smoked olive oil, can introduce a sophisticated depth to the foam.

Preparation of Watermelon Puree

  1. Cut: Slice your seedless watermelon into manageable chunks, discarding the rind.
  2. Puree: Using a blender, puree the watermelon chunks until completely smooth. This pureed watermelon will form the base of your foam.

Adding Sweeteners and Flavour Enhancers

  • Sweeten: Gradually add sugar to your watermelon puree, tasting as you go to achieve your desired level of sweetness.
  • Enhance: Stir in a small amount of lemon juice to balance the sweetness with a subtle tangy note and a pinch of salt to intensify the flavours.
  • If desired, infuse with your preferred oil to create a depth of flavour before transferring the mixture into a siphon charged with FastGas whipped cream chargers, ready for foaming.

Finalising Watermelon Foam Recipe

Creating a refreshing watermelon foam is a delightful way to add a unique touch to your summer dishes. It involves blending watermelon with certain stabilisers and aerators, followed by a precise aeration process. To ensure the best results, take heed of how to store and serve this homemade delicacy.

Incorporating Stabilisers and Aerators

Stabilisers such as pectin are essential to ensure your watermelon foam maintains its structure and consistency. They prevent the liquid from separating and help the foam hold its shape.

  • Pectin: Use 2g of powdered pectin to stabilise 300g of watermelon juice. Mix thoroughly before aerating.
  • Cream: Adding 100g of cream helps introduce fat, which is necessary for the foam to stabilise and enrich the texture.

Blending and Aeration Process

For the proper aeration process, you’ll need either a blender or a food processor to ensure a smooth puree of the watermelon.

  1. Blend seedless watermelon juice until smooth.
  2. Combine the smooth juice with the cream and powdered pectin mixture.
  3. Transfer the mixture to a cream dispenser.
  4. Attach a FastGas whipped cream charger and infuse the mixture with gas until it reaches a pressure of 10 bars.
  5. Shake well to distribute the gas evenly.

Storage and Serving Suggestions

The final step is storing and serving your watermelon foam:

  • Storage: Fill canning or other sealed jars with the foam and refrigerate. This step will preserve the foam’s texture and freshness.
  • Serving: Serve chilled as a garnish for desserts or alongside savoury dishes.


Container Type Storage Location Duration
Sealed jars Refrigerator Up to 2 days


Remember, watermelon foam is best enjoyed fresh, so plan to serve it within a couple of days of making it. Enjoy this homemade creation and the delightful burst of summer it brings to your palate.
