Greatly underrated fishes, the threadfin salmons yield thick, sizeable and essentially boneless fillets. They are often available, have a high recovery rate and can have a good shelf life.

Threadfin salmons are excellent eating when cooked in a wide variety of ways. Their firm flesh and large flakes make them absolutely ideal for barbecuing or grilling in steaks, cutlets or fillets, depending on size and variety. The flakes can also be carefully separated after grilling to enhance presentation.

The thick, firm fillets of threadfin salmons make them ideal for use as kebabs (cubed) and in soups, curries or casseroles.

Ideally suited to citrus flavours, threadfin salmons can be accom-panied by butters flavoured with herbs such as chives, tarragon and parsley. They are also superb baked, served with roasted vine-ripened tomatoes and fresh herbs.

Flavour: Mild
Oiliness: Low
Moisture: Moist
Texture: Firm
Flesh Colour: White
Thickness: Thick to medium fillets and steaks
Bones: There are bones in the fillets but they are easily removed.
Price: Threadfin salmons are medium- to high-priced finfish. King threadfin fetches a high price, blue threadfin a medium price.

Suggested Wines

Threadfin salmons are good eating, flaky, tropical finfish that readily absorb the flavours of other ingredients. Wines to match highly flavoured dishes should be light-bodied reds made in the Beaujolais style, especially with Mick McDougall s recipe from the Bonrook Lodge in the Northern Territory that serves king threadfin with vegetable fritters and tapenade
