This marlin grills very well. Before cooking the marlin make a tropical fruit salsa to accompany the grilled marlin-serve the salsa warm.
Combine liquids together in pan, heat and thicken with corn starch. When this thickens add fruit and warm all ingredients until hot. Keep warm and serve with the grilled marlin. Brush the marlin fillets or steaks with olive oil. Season these portions with fish seasoning (see the freshfish4u.com product page for this spice). If you like a spicy marlin use a Cajun Seasoning. Grill the marlin for about 4 minutes per side. If the marlin is thicker than 3/4 inches cook longer on each side.
