Frozen King Crab: the commercial format
King crab (Paralithodes camtschaticus) that reaches Europe is almost always pre-cooked frozen legs. The crab is caught in Alaska, Kamchatka, or northern Norway, immediately steam-cooked on the boat, frozen at -40°C, and shipped.
This greatly simplifies home preparation: it's already cooked, you just need to thaw and heat. It does NOT require 30 minutes of boiling like a live lobster.
Correct Thawing (key to success)
Correct method: 24 hours in the refrigerator, in its original packaging or on a tray with absorbent paper underneath.
Quick method (not ideal): hermetically sealed bag submerged in COLD water, change water every 30 min, 2-3h total.
NEVER: thaw at room temperature (bacterial risk), in hot water (ruins texture), microwave (meat cooks).
After thawing: use within a maximum of 24 hours. Do NOT refreeze.
3 Cooking Techniques for Thawed Crab
1. Steaming (recommended): steamer with boiling water, legs inside for 8-10 min. Serve hot with melted butter.
2. Quick boil: submerge legs in boiling salted water for 5 min. Drain, serve.
3. Baked with butter and garlic: legs on a tray + 80g melted butter + 4 crushed garlic cloves + lemon + parsley. Oven 180°C for 8 min. "American food" version.
How to Serve King Crab Correctly
Equipment: large wooden board, crab crackers or tongs, picks to extract meat, butter bowls, large napkins (it's "messy" food).
Classic accompaniments:
- Melted butter with lemon: 100g salted butter + juice of half a lemon + 1 crushed garlic. Serve hot in a bowl.
- Dijon mustard sauce: 100g mayonnaise + 2 tsp Dijon mustard + 1 tsp Sherry vinegar. For dipping.
