Understanding Spicy Crab – Raw vs. Cooked
Crab is a popular seafood ingredient used in sushi and Korean cuisine, but many people wonder whether spicy crab dishes are made with raw or cooked crab. The answer depends on the type of dish—while spicy crab sushi is typically made with cooked imitation crab, certain Korean seafood delicacies feature raw, marinated crab. In this section, we’ll explore the differences between these two types of spicy crab dishes, their preparation methods, and important food safety considerations.

1.1 What Is Spicy Crab?
Definition of Spicy Crab
Spicy crab refers to crab meat combined with a spicy seasoning or sauce. It is a widely used ingredient in:
✔ Sushi rolls (such as the Spicy Crab Roll or Spicy Kani Roll).
✔ Korean seafood dishes (such as Yangnyeom Gejang, a raw marinated crab dish).
While both types of spicy crab have a bold, spicy flavor, their preparation methods differ significantly.
Two Main Types of Spicy Crab Dishes
1️⃣ Spicy Crab in Sushi – Typically Cooked
- Most spicy crab sushi rolls use imitation crab (surimi), which is pre-cooked.
- Sometimes real crab is used, which may be either cooked or raw depending on the dish.
- The crab is usually mixed with spicy mayo and served in sushi rolls, salads, or hand rolls.
2️⃣ Korean Spicy Raw Crab (Yangnyeom Gejang) – Made with Raw Crab
- A Korean seafood delicacy made by marinating raw blue crab in a spicy, tangy sauce.
- The raw crab is left to ferment for several days in the refrigerator before serving.
- Known for its soft, jelly-like texture and bold umami flavor.
Understanding these two different spicy crab preparations helps clarify whether a particular dish contains raw or cooked crab.
1.2 Spicy Crab in Sushi – Cooked or Raw?
Spicy Crab Sushi Rolls Use Cooked Ingredients
If you’ve ever ordered a Spicy Crab Roll or Spicy Kani Roll, you’ve likely eaten cooked crab.
- Most sushi restaurants use imitation crab (surimi), which is always pre-cooked.
- The imitation crab is shredded and mixed with spicy mayo, creating a creamy, slightly spicy filling.
- Some variations include avocado, cucumber, or sesame seeds for extra flavor and texture.
Real Crab Sushi – Cooked or Raw?
While spicy crab sushi typically uses imitation crab, some restaurants offer sushi with real crab instead.
- Cooked real crab sushi is common in high-end sushi rolls.
- Raw real crab (sashimi-style) is rare but can be found in some specialty sushi dishes.
Why Raw Crab Is Rare in Sushi
Unlike salmon or tuna, crab is not a typical raw ingredient in sushi. Here’s why:
🚫 Soft Texture – Raw crab has a soft, gelatinous texture, which doesn’t hold up well in sushi rolls.
🚫 Food Safety Risks – Raw crab can contain bacteria or parasites if not handled properly.
🚫 Most Crab Sold in the U.S. Is Pre-Cooked – This is done for safety reasons, so raw crab sushi is not commonly found.
Key Takeaway:
✔ Spicy crab in sushi is almost always cooked, either as imitation crab or real crab meat.
✔ Raw crab is rare in sushi due to safety concerns and texture differences.
1.3 Korean Spicy Raw Crab (Yangnyeom Gejang) – A Raw Delicacy
What Is Yangnyeom Gejang?
Yangnyeom Gejang (양념게장) is a traditional Korean dish made with raw blue crab marinated in a spicy, umami-rich sauce. Unlike spicy crab in sushi, this dish is intended to be eaten raw, allowing the marinade to preserve and enhance the crab’s natural sweetness.
How Yangnyeom Gejang Is Prepared
To safely enjoy raw crab, proper cleaning, marinating, and refrigeration are essential.
✔ Step 1: Choosing the Right Crab
- Typically made with fresh blue crabs from clean waters.
- The crabs are cleaned thoroughly and frozen for a few hours to kill potential parasites.
✔ Step 2: Making the Spicy Marinade
- The crabs are marinated in a mixture of:
🔥 Gochugaru (Korean chili flakes) – Adds heat
🍯 Sugar – Balances the spice with sweetness
🧄 Garlic & Ginger – Enhances umami flavor
🍋 Soy sauce & Rice vinegar – Adds tanginess
✔ Step 3: Marinating & Fermenting
- The crabs are left to marinate in the refrigerator for 3-5 days.
- During this time, the marinade penetrates the crab meat, giving it a bold, rich flavor.
Taste & Texture of Yangnyeom Gejang
🦀 Flavor Profile: Sweet, spicy, umami-rich, and slightly tangy.
🦀 Texture: Soft, jelly-like, and tender—very different from cooked crab.
🦀 Best Served With: Hot white rice and sesame oil for dipping.
Is It Safe to Eat?
Raw seafood always comes with potential food safety concerns, but proper handling minimizes the risks.
✔ Choose high-quality, fresh crab from a trusted seafood market.
✔ Always freeze crab for a few hours before preparing.
✔ Consume within 2-3 days for optimal freshness.
Key Takeaway:
✔ Yangnyeom Gejang is a raw crab dish that requires careful preparation and marinating.
✔ It has a unique texture that is very different from cooked crab or spicy crab sushi.
✔ Proper handling and freshness are crucial for food safety.
How to Safely Eat & Prepare Spicy Crab
Spicy crab can be both raw and cooked, depending on the dish. While spicy crab sushi is typically made with cooked ingredients, Korean spicy raw crab (Yangnyeom Gejang) is eaten raw. Proper handling, preparation, and storage are essential to ensure food safety when consuming crab, especially when raw.
2.1 Is It Safe to Eat Raw Crab?
Raw crab is not as commonly eaten raw as fish because it can carry parasites and bacteria if not handled properly. However, some cuisines, such as Korean and Chinese cooking, feature raw crab dishes.
Potential Risks of Eating Raw Crab
🦀 Parasites & Bacteria – Raw crab can contain harmful bacteria like Vibrio and parasites that may cause foodborne illness.
🦀 Proper Sourcing is Crucial – Raw crab should be extremely fresh and purchased from trusted seafood markets.
🦀 Storage Matters – Keeping raw crab at the correct temperature (below 40°F/4°C) helps prevent bacterial growth.
Why Raw Crab Isn’t Commonly Used in Sushi
Unlike salmon or tuna, crab is rarely eaten raw in sushi for several reasons:
🚫 Texture Issues – Raw crab has a soft, gelatinous texture, which doesn’t hold up well in sushi rolls.
🚫 Safety Concerns – Most seafood used in sushi is flash-frozen to kill parasites, but crab is not always treated this way.
🚫 Cooking Enhances Flavor – Crab meat develops a sweeter, more pronounced taste when cooked.
How Korean Cuisine Safely Uses Raw Crab
In dishes like Yangnyeom Gejang, raw crab is marinated in a spicy sauce, which helps preserve the crab and reduce bacterial risks. Proper handling ensures it’s safe to eat, but it should be consumed within a few days.
🔹 Key Takeaway: Raw crab should be handled carefully, and if you’re unsure, it’s always safer to choose cooked crab for sushi and other dishes.
2.2 How to Make Spicy Crab for Sushi (Cooked Version)
Since raw crab is not typically used in sushi, most spicy crab sushi dishes feature imitation crab (surimi) or cooked real crab. The spicy crab mixture is creamy, slightly spicy, and perfect for sushi rolls, hand rolls, and salads.
Step-by-Step Preparation for Spicy Crab Sushi
✔ Step 1: Shred the Crab
- If using imitation crab (surimi), gently pull apart the pieces into thin strands.

🔥 1 tbsp sriracha (adjust for spice level).
🔥 1 tsp soy sauce (for umami flavor).
🔥 1/2 tsp sesame oil (adds depth and nuttiness). - Stir until fully combined.
✔ Step 3: Combine with Crab
- Fold the shredded crab into the spicy mayo mixture until evenly coated.
- Add a splash of lemon juice for extra freshness (optional).
✔ Step 4: Use in Your Favorite Sushi Dish
- Roll into spicy crab sushi rolls with rice and nori.
- Use as filling for hand rolls (temaki).
- Serve as a spicy kani salad with cucumbers and avocado.
Variations of Spicy Crab for Sushi
🍣 Spicy Kani Salad – Instead of rolling into sushi, serve the spicy crab mixture as a cold salad, topped with cucumbers, avocado, and sesame seeds.
🔥 Baked Spicy Crab Roll – Add spicy crab mixture on top of a sushi roll, bake until warm, and drizzle with eel sauce.
🔹 Key Takeaway: Spicy crab sushi is always made with cooked crab, either imitation or real. It’s easy to prepare at home and can be used in various sushi dishes.
2.3 How to Prepare Korean Spicy Raw Crab (Yangnyeom Gejang)
