Strawberry Lychee Watermelon Slush Cooler with Whipped Cream Step-by-step instructions

Before you start

Before you start, chill the hibiscus tea completely, at least two hours in the refrigerator, so it does not dilute the slush. Wash the watermelon, strawberries and limes, and have the lychees peeled and drained. Set out the blender, chef's knife, cutting board, box grater, clear glasses and piping bag. Chill the heavy cream and a small bowl in the freezer for 10 minutes so the cream whips faster and holds its shape.

Wrap the white chocolate and place it in the refrigerator for a short while so it grates into fine curls rather than smearing. Lay out a clean towel or plate to catch the grated chocolate. Prepare everything in advance so you can move quickly from blending to serving, because the slush is best served within minutes of making it.

Instructions

Cut and grate the fruit

1. 1Cut the watermelon and fruit
   Slice the watermelon into wedges, then cut the flesh into 1-inch cubes on a cutting board. Hull the strawberries, peel the lychees, and set aside a few sliced strawberries for layering. Keep all the fruit cold until blending.
   Look for Watermelon cubes are firm, neat and evenly sized, with no loose pieces of rind.
   Tip Chilled fruit gives a colder slush without watering it down.
2. 2Grate the white chocolate
   Hold the white chocolate against the fine side of a box grater and grate it over a plate or the board until you have a small pile of fine white curls for the top.
   Look for Fine white curls fall lightly with no large chunks left behind.
   Tip Chill the chocolate for 10 minutes first so it grates cleanly.

At the end of this phase, the watermelon should be in neat, firm cubes, the strawberries hulled and the lychees peeled and drained. The white chocolate should have produced a light pile of fine white curls. Nothing should be sticky or leaking juice onto the board.

Check that the fruit is cold and the chocolate is well chilled before you move on to the blender. If the watermelon looks soft or the fruit is warm, return it to the refrigerator for ten minutes. Cold ingredients make a thicker slush and keep the finished drink crisp, so this short pause saves you from a watery result later.

Blend until smooth

3. 3Blend the slush
   Add the watermelon cubes, strawberries, peeled lychees, hibiscus tea and ice to the blender jar. Lock the lid in place and blend until smooth and vivid pink, with no visible chunks.
   Look for The slush is smooth, bright pink and pours thickly without solid pieces.
   Tip Pulse first to break up the ice, then blend on high until smooth.
4. 4Layer the glass
   Pour the slush into a clear glass. Add a spoonful of sliced strawberries and a few extra pieces of fruit so the chunks show through the drink.
   Look for Fruit pieces are visible through the glass in the pink slush.
   Tip Set the fruit against the glass side so it shows clearly.

At the end of this phase, the slush should be smooth, vivid pink and pourable, with no visible chunks of fruit or ice. Lift the lid and look at the surface: it should be even and glossy. Scrape the sides of the jar and blend again for a few seconds if any pieces remain. The texture should be thick enough to hold a spoon standing upright but still smooth enough to pour. If it is too stiff, add a splash of chilled hibiscus tea and blend briefly. The color should be bright and even throughout, with a cool, frosty feel.

Layer, top and serve

5. 5Top with cream and chocolate
   Whip the heavy cream to soft peaks and pipe a generous swirl on top of the slush using a piping bag. Finish with a light shower of grated white chocolate.
   Look for The cream holds a soft swirl and the chocolate curls sit on top of it.
   Tip Chill the cream and bowl before whipping for stiffer peaks.
6. 6Serve with lime
   Add a lime wedge to the rim of each glass and serve right away, with a spoon or straw, before the slush softens.
   Look for The cream is still firm and the drink is icy and cold.
   Tip Serve immediately so the slush stays thick and cold.

At the end of this phase, each glass should show a clear pink slush with strawberry pieces and fruit visible through the sides, a generous swirl of firm whipped cream on top and a light scattering of white chocolate curls. Check that the cream holds its shape and that the chocolate is on top rather than sunk into the drink. The lime wedge should sit on the rim and the glass should feel cold to the touch. Serve immediately, while the slush is still thick and the cream is still firm, so each guest gets the best texture and presentation.

Common mistakes

The most common mistake is blending the slush too long, which warms the mixture and turns it watery before you have a chance to serve it. Blend in short bursts, check the texture, and stop as soon as it is smooth. Another common problem is using warm hibiscus tea or warm fruit, which melts the ice quickly and leaves the drink thin.

Chill every liquid and fruit component before you start. Overloading the blender with ice can also leave large chunks behind, so keep the ice measured and blend the fruit first if your machine struggles. Be careful with the whipped cream: overwhipping makes it grainy and stiff, while underwhipping makes the swirl collapse on the slush. Stop when the cream holds soft peaks.

How to tell it’s done

This drink has no cooking temperature to reach, so you judge it by texture and appearance. The slush is ready when it is completely smooth and an even bright pink, with no visible pieces of watermelon, strawberry, lychee or ice. It should pour slowly from the jar and thicken as it sits. When you lift the blender lid, the surface should look glossy and uniform.

The whipped cream is ready when it holds a soft, defined swirl that stands up on the surface of the drink without slumping. The white chocolate should be finely grated, with delicate curls on top rather than heavy chunks. Serve when all three elements look this way, while the drink is still icy and cold.
