  • 4 x 200g/7oz pieces of good quality ahi tuna
  • 110g/4oz orange marmalade or apricot jam
  • Gluten free soya sauce (like Tamari) – 1 tbsp
  • 1 tsp cumin seeds, sightly crushed
  • Plus, 1 tsp coriander seeds, lightly crushed

Preparation method:

  1. For the tuna, place the tuna onto a plate.
  2. Whisk the apricot jam or marmalade, gluten free soy sauce, coriander seeds and cumin seeds together in a bowl with salt and freshly ground black pepper. Pour the mixture over the tuna and turn it over to ensure it is well coated in the marinade.
  3. Set aside to marinade for at least 30 minutes. You can marinate longer if you want a more intense flavour.
  4. Heat a griddle pan until hot. Place the tuna onto the griddle and cook for one minute, turn it 90 degrees and cook for a further minute. Turn the fish over and cook for another 1-1½ minutes (for rare). Remove the tuna from the pan and set aside to rest for one minute. Slice into thin slices and enjoy.

An important note to remember is to always use fresh tuna. Your local fishmonger should be able to tell you when the fish was caught and where.  Incorporating tuna into your diet is a great way to get more Omega 3’s and keep you energized and alert.  Due to issues around mercury content, people should limit their intake to two to three portions a week.  Pregnant women should avoid eating too much tuna and should keep away from raw fish altogether just to be on the safe side.
