How to make a watermelon shark

We're always up for getting creative with our food, so we had to give this fun trend a go. All you need is a watermelon and a couple of small, dark fruits – and voilà, you've created a mouth-watering masterpiece.

Make your own scary summer treat by following the steps below – and don't forget to tag @asda and #GetYourCookOn on Insta when you do!

what you need

  • 1 large watermelon
  • 2 large blueberries (can swap out for another dark fruit, like black olives or grapes)



  1. Make sure you have a solid surface to work on. Wash and dry a large watermelon, then put on a chopping board.
  2. Find the more pointed ‘top’ end of the watermelon. Hold this steady and use a large, sharp knife* to slice off the bottom quarter of the melon, at a slight diagonal. You need to create a flat base, with the top – which will form the shark’s snout – pointing up at an angle. Reserve the cut-off piece to make the fin.
  3. Stand the watermelon up on its cut side, then use the tip of a metal skewer to mark a mouth shape – this should be fairly large, but with enough space both above and below it for teeth about 3-5cm long. Using the line as a guide, remove a wedge of the melon – scoop out the flesh from the wedge and discard the rind. Your shark now has a large, open mouth.
  4. To make watermelon slush, use a spoon to scoop most of the red flesh out of the melon – leave a 2cm-thick layer in place for colour and to make sure your shark is sturdy. Freeze all the scooped-out flesh in freezer bags for 3-4 hrs. (If time is short, or if you prefer fresh watermelon, you can remove the red flesh with a melon baller or spoon.) 
  5. Meanwhile, for the teeth, mark lines 3-5cm above and below the mouth-opening, following its shape. With a small, sharp knife, trim off the green outer peel to reveal the softer white rind beneath it – take care not to cut too deeply.
  6. Carefully cut triangular pieces out of the white rind to create sharp, pointed teeth.
  7. Mark the position of the shark’s eyes with a skewer, then cut shallow ‘sockets’ to hold them – an apple corer is ideal for this, or use a small knife. For the eyes, use 2 large blueberries (or black olives, or grapes), secured in place with cocktail sticks. 
  8. Cut a fin shape from the reserved melon base and secure to the back of the shark with cocktail sticks.
  9. Transfer the shark to a serving tray or platter – bonus points if it’s ocean blue! For the slush, wrap the bags of frozen watermelon in a clean tea towel and bash with a rolling pin to crush. Fill the mouth with the slush – or fresh watermelon, if using. Serve with a big, toothy grin.
