  • 1 mini watermelon, skin removed, 50g reserved for the dressing, rest sliced into triangular wedges
  • 200g green beans, trimmed
  • 4 salad onions, finely sliced diagonally
  • 1 cucumber, deseeded and thinly peeled into long strips with a peeler
  • ½ x 25g pack mint, leaves picked
  • ½ x 25g pack coriander, leaves picked
  • 50g cashew nuts, toasted and roughly chopped
  • 30g Cooks' Ingredients Crispy Fried Onions
  • 4 whole mackerel (available from the fish service counter)
  • 2 tbsp rapeseed oil


  • 2 red chillies
  • 2 clove/s garlic
  • 2 tbsp palm sugar
  • 1 tbsp tamarind paste
  • 2 tbsp lime juice
  • 2 tbsp fish sauce


  1. First make the dressing. Finely chop the red chillies and garlic. In a food processor, whizz them together with a little water (about 3 tbsp) until you have a paste. Add the sugar and 50g watermelon and whizz again until smooth. Stir in the tamarind, lime juice and fish sauce.

  2. Bring a pan of salted water to the boil, then blanch the beans for 4-5 minutes until just tender but still vibrant green. Drain, transfer to a bowl of iced water, then drain again and put in a large bowl. Add the remaining watermelon and the vegetables to the bowl along with the herbs, cashews and the dressing; toss together. Transfer to a serving platter and sprinkle over the crispy fried onions.

  3. Heat a large griddle pan (or barbecue) until very hot. Score each side of the mackerel about 6 times. Brush the fish with the oil and season. Cook the mackerel on the griddle or barbecue for 4-5 minutes on each side until charred, cooked through, opaque and the eyes have turned white. Serve at once with the rojak.
