Spot Prawn
Large sweet cold-water prawn prized for delicate, almost lobster-like flesh; cooks fast, so it is best lightly grilled, seared, or even eaten raw when very fresh.
The spot prawn (Pandalus platyceros) is the largest and most celebrated of the cold-water pandalid shrimp on the Pacific coast, and arguably the most luxurious wild shrimp in North American waters. Found from the Aleutian Islands down to Baja California, it lives on deep, muddy bottoms in frigid water, and that cold upbringing is what gives the meat its famously clean, sweet, almost lobster-like flavor. There is no significant aquaculture — virtually every spot prawn you buy is wild, and the British Columbia May trap fishery is treated almost as a seasonal event on the West Coast, with live prawns sold off small boats within hours of being hauled up.
What separates spot prawns from the warm-water farmed shrimp that dominate supermarket cases is texture. The flesh is dense but tender, with a soft, almost custardy bite when handled correctly, and a sweetness that fades the moment heat lingers. The cooking window is short — 60 to 90 seconds is usually enough for a quick sear, and even on a hot grill the meat is finished in well under two minutes total. The shells, which shift from translucent grey-green to a brilliant coral pink the instant they hit heat, are thin and fragile, and the heads hold a richly flavored hepatopancreas sometimes called "tomalley."
For a cook, the brief is simple: get them as fresh as you possibly can, season them simply, and apply the least amount of heat the dish will allow. Whether that means a 30-second sear in foaming butter, a single minute over a charcoal grill, or a clean slice for sashimi, the prawn should still feel almost translucent in the center when served.

Types & varieties
Trap-caught along the BC coast; the most celebrated fishery, May–June season; live prawns sold direct off small boats in May.
Same species, harvested by pot year-round in the Gulf of Alaska though most available spring–fall; tends to run a bit smaller on average.
Same species; managed by state fisheries with recreational pot seasons in spring.
Southern end of the range; caught along the Central and Southern California coast, peak May–October.
Recently molted; softer, more fragile shell, more translucent flesh, very tender — best for raw preparations or a flash poach.
Well-developed shell; firmer, snappier texture and more concentrated sweet flavor — the classic choice for grilling whole.
Soft-Shell vs. Hard-Shell: Pick the Right Prawn for the Job
A spot prawn's shell tells you how to treat it. Soft-shells, common in early season, are animals that have just molted: the carapace is pliable, almost papery, and the meat underneath is more translucent and a touch sweeter, but also more fragile. They soak up brine, lose moisture quickly, and will fall apart on the grill. Reserve them for raw applications — sashimi, crudo, ceviche — or for a brief poach in court bouillon.
Hard-shells are the classic grilling prawn: firmer, snappier, and able to take 60 to 90 seconds of direct heat without disintegrating. The flavor is also a touch more concentrated, because the animal has had longer to mature its hepatopancreas. When you have the choice, pick hard-shells for the grill, soft-shells for the knife.
Heads, Shells, and Stock: Don't Throw Any of It Away
The byproduct of a spot prawn is arguably more valuable than the tail. The head and carapace hold the hepatopancreas, a rich, orange-tinted fat that carries most of the prawn's savory depth.
- Brown the heads and shells in butter or olive oil, deglaze with dry white wine or sherry, and reduce for a quick pan sauce to drape over the tails.
- Roast the shells hard, simmer with aromatics for a bisque base, and finish with cream and a splash of brandy or Pernod.
- Infuse warm butter with crushed heads, garlic, and chili for a compound butter to melt over grilled tails, pasta, or bread.
- Stocks keep 3 days refrigerated or 3 months frozen; strain through a fine mesh and reduce for sauces, risottos, and seafood soups.
Common uses
Tips & pitfalls
- Cook spot prawns for 60–90 seconds total — the most common mistake is overcooking, which turns the sweet flesh rubbery and the shells chalky within seconds.
- Buy them alive or freshly killed; live prawns twitch when touched and should smell of clean seawater, never ammonia or 'fish.'
- Keep on a bed of ice in the fridge with a damp towel over them; do not submerge in freshwater or seal them in an airtight bag.
- If eating raw, freeze at -20°C (or lower) for at least 24 hours first to reduce parasite risk, then thaw slowly in the refrigerator.
- For whole-grilled presentations, twist and pull off only the head and leave the shell and tail intact — the shell protects the delicate meat from the fire.
- Deveining is optional for small to medium prawns but recommended for larger specimens, where the digestive tract can taste gritty.
- Finish with flaky sea salt (Maldon or similar) just before serving; spot prawns' sweetness is amplified by a final, generous seasoning.
- Pass on any prawn with blackened gills, a soft head, or a sour smell — spot prawns deteriorate faster than warm-water shrimp and there is no rescuing them once they turn.

- Highly perishable; keep on ice, ideally cook the day of purchase, otherwise ≤2 days refrigerated
- Sustainability
- Low mercury; BC trap fishery has held MSC certification (varies by year); US West Coast pot fisheries generally well-managed
Substitutes
- Langoustines (Nephrops norvegicus) — Closest match in cold-water sweetness and lobster-like texture; smaller than spot prawns, but excellent in nearly any preparation.
- Maine or Maritime cold-water shrimp (Pandalus borealis) — Smaller but with a similar sweet, delicate flavor profile; great in pasta, salads, and bisque.
- Live lobster tail or claw meat — Not a prawn, but the closest textural stand-in and a luxury upgrade for raw or briefly cooked applications.
- King prawn or giant tiger prawn — Larger and more robust-flavored; works grilled or in dishes that call for a bigger prawn, but lacks the same sweet delicacy of spot.
- Pacific white shrimp — Inexpensive, neutral, and widely available; a reasonable fallback when spot prawns are out of season or over budget.
