How to Make Spicy Raw Marinated Crab
-
Thaw thoroughly. Begin by placing your frozen crabs in the refrigerator for several hours or overnight. If you’re short on time, rinse them under cold water until they’re defrosted.
-
Prepare the crabs. Using scissors or a sharp knife, cut the crab body in half. Trim off the thin legs and pointy parts of the claws, then crack the claws to allow the sauce to penetrate deeper. Rinse the crab pieces in cold water and drain.
-
Marinate briefly. Drizzle soju (or your diluted vinegar mixture) evenly over the crabs and let them drain again.
-
Combine flavors. In a large bowl, add the crab pieces. Pour soy sauce and Korean fish sauce over the meaty areas, tossing well. Marinate the crab in the fridge for about 20 minutes to soak in the flavors.
-
Mix the sauce. In a separate bowl, combine the soy sauce mixture from the marinade with Korean chili flakes, corn syrup, plum extract, garlic, ginger, and sugar. Stir until everything is well incorporated.
-
Coat the crab. Pour the sauce generously over the crab, and then add the sliced onion and fresh chilies. Use two spatulas to toss the crab, ensuring it’s evenly coated with the flavorful sauce. Finish with chopped green onion and toasted sesame seeds for a beautiful presentation.
-
Serve chilled. Enjoy the crab immediately or let it chill in the fridge for about 2 hours for a refreshing dish. Serve cold alongside rice to balance the flavors.
Optional: Garnish with extra sesame seeds for a delightful crunch.
