Rhubarb chutney with mackerel and watercress


For the chutney
  • 1 tbsp vegetable oil
  • 15 fresh curry leaves (available from some supermarkets and from Asian grocers)
  • ½ tsp mustard seeds
  • 400g/14oz rhubarb, finely sliced
  • 4 green chillies, chopped
  • 1 tsp ground cumin
  • 1 tsp ground coriander
  • 2 tbsp palm sugar (substitute golden caster sugar if unavailable)
  • 1 lime, juice only
  • 3 tbsp finely chopped fresh mint
For the mackerel
  • 4 mackerel, cleaned and filleted
  • 75g/3oz red watercress, leaves only
  • 75g/3oz watercress, leaves only
  • 2 tbsp extra virgin olive oil
  • salt and freshly ground black pepper

Preparation method

  1. For the chutney, heat the oil in a non-reactive frying pan and add the curry leaves and mustard seeds. When they start to crackle, add the rhubarb, chillies, cumin, coriander and palm sugar, stirring well to combine. Cook for 2-3 minutes, then add the lime juice and cook for a further 2-3 minutes, or until the rhubarb is softened. Stir in the mint leaves, then remove the pan from the heat and set aside.

  2. For the mackerel, preheat the grill to high.

  3. Place the mackerel fillets skin-side up onto a rack and cook under the grill for 4-5 minutes, or until the skin is crisp and the fish cooked through.

  4. To serve, place the watercress leaves into a bowl and toss with the extra virgin olive oil and season with salt and freshly ground black pepper. Divide the watercress equally among four serving plates, then arrange two mackerel fillets on top of each pile. Spoon the chutney alongside and serve.
