King Crab Legs with Clarified Herb Butter

Name: King Crab Legs with Clarified Herb Butter
Prep time: 15 min
Cook time: 10 min
Total time: 25 min
Yield: 4
Cuisine: Alaska
Ingredients: 1.8 kg, 4 clusters Wild Alaskan red king crab legs and claws, pre-cooked, thawed in the fridge 18 hours; 250 g Unsalted butter, to clarify; 20 g Garlic, smashed; 15 g Fresh dill, finely minced; 2 whole Lemons, one sliced for the pot, one cut in crowns for the table; 250 ml Dry white wine; 750 ml Water; 10 g Coarse sea salt, for the steaming liquid; 2 g Smoked sweet paprika

Bering Sea red king crab is cooked and blast-frozen on the boat, so at home it is reheated, never boiled. Thawed eighteen hours, snipped at the knuckles and pre-split along the soft underside, then steamed six to eight minutes over white wine, lemon and dill to 55 to 60 °C, and served with clarified butter steeped with garlic, dill and smoked paprika.

A pile of bright red king crab legs, one split open to show snow-white meat, with a lemon half and a bowl of golden butter, snowy mountains behind.

Red king crab comes out of the freezing depths of the Bering Sea and Bristol Bay, hauled from pots set a hundred fathoms down in winter gales off Dutch Harbor. It is prized for a colossal leg span and sweet, dense meat.

Because the catch is cooked and blast-frozen on the processing vessel, cooking it at home is a matter of gentle reheating. Boiling washes the sweetness into the pot. Coastal kitchens steam the clusters over a court-bouillon of white wine, lemon, salt and dill, and serve the cracked legs with warm clarified butter.

Ingredients

1.8 kg, 4 clustersWild Alaskan red king crab legs and claws, pre-cooked, thawed in the fridge 18 hours
250 gUnsalted butter, to clarify
20 gGarlic, smashed
15 gFresh dill, finely minceddivided
2 wholeLemons, one sliced for the pot, one cut in crowns for the table
250 mlDry white wine
750 mlWater
10 gCoarse sea salt, for the steaming liquid
2 gSmoked sweet paprika

Reheat, do not cook

Commercial king crab is already cooked to 63 °C at sea. Boiling it leaches the sweet amino acids, glycine and alanine among them, into the water. Steam warms the meat through the shell while the flavour stays inside.

Why clarify

Clarifying removes the water and milk solids, so the butter stays clear and golden instead of turning milky or greasy in the ramekin.

The five tastes on this plate

Salt is the crab's own sea salinity and the salted steam. Fat is the drawn butter. Acid is lemon in the pot and on the table. Heat is steeped garlic and a dust of smoked paprika. Umami is the glycine and glutamate of deep cold-water crab.

Equipment

16-quart stockpot with a steamer insert
Kitchen shears
Small saucepan and a warm ramekin
Digital probe thermometer
Crab forks

A big camp stockpot with a raised steam insert over a propane cooker is the Alaskan setup. A wide roasting pan with a rack and a foil lid, or a tiered steamer, works. The crab must sit two inches above the liquid.

Method

Thaw and section18 hr
Thaw the clusters on a rimmed tray in the fridge 18 hours, never in warm water. Separate the legs at the knuckles with shears and snip along the soft white underside of each shell to pre-split it.
Thaw pre-cooked crab on a rimmed tray in the fridge for 18 hours, never in warm water. Separate legs at knuckles with shears; slit each shell along its soft white underside.
Set up the steam5 min
Combine the water, wine, lemon slices, salt and half the dill in the stockpot. Set the steamer basket in with the liquid at least 2 inches below it. Cover and bring to a rolling boil.
Combine water, wine, sliced lemon, salt and half the dill in the stockpot. Keep liquid at least 2 inches below the steamer basket; cover and bring to a rolling boil.
Clarify the butter6 min
Melt the butter in the saucepan over low heat without stirring. Skim the white foam. Pour the clear golden fat into a warm ramekin, leaving the water and milk solids behind. Whisk in the garlic, remaining dill and paprika. Hold at about 50 °C.
Melt butter on low without stirring; skim foam. Pour clear fat into a warm ramekin, leaving water and milk solids behind. Whisk in garlic, remaining dill and paprika; hold around 50 °C.
Steam8 min
Arrange the crab in the basket in a loose lattice so steam moves through it. Cover tightly and steam over medium-high 6 to 8 minutes, 10 for colossal legs over 450 g each.
Arrange crab loosely in the basket so steam circulates. Cover tightly; steam over medium-high 6–8 minutes, or 10 minutes for colossal legs weighing over 450 g each.
Check the temperature1 min
Probe the thickest upper-leg meat: 55 to 60 °C. Above 65 °C the meat turns stringy and sticks to the shell.
Probe the thickest upper-leg meat for 55–60 °C. Avoid exceeding 65 °C, when the meat becomes stringy and sticks to the shell.
Serve
Tip the hot legs onto a paper-lined platter with shears and crab forks. Serve with the warm garlic-dill butter and lemon crowns.
Transfer hot legs to a paper-lined platter. Provide shears and crab forks; serve with warm garlic-dill butter and lemon crowns.

Sensory cues of doneness
- Visual: shells vivid crimson-orange; meat snow-white with scarlet flecks; the butter clear liquid gold.
- Auditory: shells rattling in the basket, wine steam hissing under the lid.
- Olfactory: clean ocean, sweet shellfish, melted butter, lemon and dill.
Look for vivid crimson-orange shells, snow-white meat with scarlet flecks and clear golden butter. Expect rattling shells, hissing steam and ocean, sweet shellfish, butter, lemon and dill aromas.

Troubleshooting

Waterlogged, bland crab.: It was boiled. Keep pre-cooked crab above the liquid and let steam do the work.
Meat welded to the shell.: Overheated past 70 °C. Six to eight minutes, and pull at 55 to 60 °C.
Cloudy, watery butter.: The milk solids and water came along. Melt gently and decant only the clear fat.

Substitutions

One-to-one swaps, with the technique change each one needs.

Ingredient substitutions

Ingredient	Replace with	Culinary impact and technique adjustment
Red king crab	Bairdi or snow crab	Thinner legs; steam only 4 to 5 minutes
Clarified butter	Cultured butter or garlic-infused olive oil	Slightly more moisture in the dip
Dry white wine	Water with 2 Tbsp white wine vinegar	Keeps the acidity in the steam without alcohol

Scaling

Half

900 g of crab in an 8-quart pot with a rack. Steam 6 minutes.

Double

3.6 kg in two batches or two pots. Packed tight, steam cannot reach the centre clusters.

What to serve it with

Roasted baby red potatoes with sea salt, and sweet corn on the cob
Sourdough bread and a crisp green salad
An Alaskan white ale, or a brut sparkling wine

Questions

Can I steam it from frozen?

Yes, but an overnight fridge thaw gives better texture. From frozen, add 4 to 5 minutes and check with a probe.

Why pre-split the shells?

King crab shells are spiny. A cut along the soft underside lets guests open them without tearing the meat.

Red or golden king crab?

Red has wider, heavier legs, a deeper orange colour and fewer spines along the ridge. It is the sweeter of the two.
