Method
Using a sharp chef's knife on a clean cutting board, slice 2 lemons and 2 limes crosswise into 6 mm (1/4 inch) thick round wheels, setting aside the remaining 1 lemon and 1 lime for zest and juice.
Finely grate the zest of the remaining 1 lemon and 1 lime with a microplane zester directly into a small bowl, collecting only the colorful outer peel and avoiding the bitter white pith.
Finely chop 20 g of the fresh lovage leaves on the cutting board, setting aside the remaining 10 g of whole sprigs to use on the grill.
Halve the zested lemon and lime, extract their juice using a citrus juicer into the small bowl with the zest, add the minced lovage, and stir the mixture with a spoon until combined.
Pat the 4 bluefish fillets dry on all sides using paper towels, place them skin-side down on the cutting board, and season the flesh evenly with 6 g of fine sea salt. Allow the fillets to rest at room temperature for 15 minutes so the salt dissolves and firms the flesh. Wash hands, cutting board, and knife thoroughly with hot soapy water after handling raw fish to prevent cross-contamination.
Preheat the outdoor grill on medium-high heat to an ambient chamber temperature of 200°C to 230°C (400°F to 450°F), then scrub the grates thoroughly with a grill brush.
Using tongs, arrange the lemon and lime wheels across the direct heat zone of the grill grate in a dense, overlapping rectangle matching the footprint of the fish, scatter the 10 g of reserved lovage sprigs over the citrus, and place the salted bluefish fillets skin-side down directly on top of the citrus bed. Close the grill lid and cook undisturbed for 10 to 12 minutes, until the flesh turns opaque throughout, flakes readily when pressed gently, and reaches a safe internal temperature of 63°C (145°F) at the thickest point on an instant-read digital food thermometer.
Slide a wide fish spatula underneath the charred citrus wheels and lift each bluefish fillet along with its caramelized fruit base onto a warm serving platter, discarding any overly blackened rind slices.
Stir the fresh citrus-lovage mixture in the small bowl, spoon it evenly over the top of the hot grilled bluefish fillets, and serve immediately.
Chef's Notes
- Bluefish (Pomatomus saltatrix) has a naturally high fat content (around 7 to 10 percent lipids), which makes supplementary cooking oils unnecessary when grilled over a protective bed of juicy citrus wheels.
- Grilling directly over overlapping citrus rounds prevents flare-ups from rendered fish fat, completely avoids sticking, and perfumes the flesh with caramelized citrus oil vapors.
- Lovage (Levisticum officinale) contains volatile compounds such as ligustilide that yield an intense celery-anise-parsley flavor profile, which effortlessly cuts through the bold, oily profile of bluefish.
- Salting the fish 15 minutes prior to cooking facilitates light surface protein denaturation, drawing moisture back in while firming the delicate flesh so it holds its shape during grilling.
Storage
Refrigerator: 2 days — Store in an airtight glass container at or below 4°C (40°F) within 2 hours of cooking.
Freezer: 1 month — Freeze in a vacuum-sealed bag or airtight freezer container at -18°C (0°F), though texture will soften upon thawing.
Reheating: Reheat gently in an oven or covered skillet at 135°C (275°F) until the internal temperature reaches 74°C (165°F) as measured with a food thermometer.
Troubleshooting
Fish flesh turns mushy or has an aggressively strong fishy odor
Cause: Bluefish was held at warm temperatures before cooking or was not fresh, leading to enzymatic breakdown of delicate omega-3 oils
Fix: Cannot be fixed once degraded, but spooning extra fresh lime juice and lovage over the fillet helps temper lingering fishiness
Prevention: Procure freshly caught bluefish that smells cleanly of the ocean and keep it submerged in ice within the refrigerator until 15 minutes before cooking
Fish sticks to the grill and tears when lifting
Cause: Fillets made direct contact with bare metal grates rather than resting squarely atop the citrus slice bed
Fix: Slide a thin fish spatula carefully between the grill grate and the charred citrus, lifting the fruit together with the fillet
Prevention: Ensure the lemon and lime wheels overlap tightly to form a complete fruit barrier between the fish skin and the grill grates
Fish has not reached 63°C (145°F) after 12 minutes of grilling
Cause: Grill chamber heat was lost due to frequent lid opening or low burner settings
Fix: Close the grill lid immediately and continue grilling in 2-minute intervals until the digital food thermometer registers 63°C (145°F)
Prevention: Maintain grill lid closure throughout cooking to retain hot ambient convection air around the fish
Cultural Context
Bluefish is a classic Atlantic game fish long celebrated along the eastern seaboard of the United States, particularly across coastal New England and Long Island. Because its oily, dark-meated flesh possesses a assertive ocean flavor, coastal cooks have historically relied on tart citrus juices and pungent backyard herbs to achieve balance. Lovage, a heirloom culinary herb cultivated in colonial gardens for its intense savory brightness, offers an old-world herbal counterpoint that elevates this minimalist summer catch.
