Sharp and sweet fruit flavours work particularly well with mackerel as it’s a rich and oily fish. It’s also perfect for the barbecue - quick to cook and full of flavour.

2. Score each mackerel a few times on each side, without cutting through to the bone. Rub the marinade all over the mackerel. Season with salt and set aside for 15-20 minutes.​​​​​​​

5. Light two gas burners on the Jupiter Outback BBQ. Once it’s really good and hot, place the mackerel on the grill and cook for 3-5 minutes each side, or until just cooked through. The key with cooking fish is to wait for the fish to release itself from the grill before turning - this way you won’t leave the skin behind.​​​​​​​

6. Dress the salad and serve with the mackerel and lemon wedges on the side.​​​​​​​
