Introduction

Yangnyeom gejang (양념게장) is raw crab coated in a thick, glossy chili sauce. It is the spicy sibling of ganjang gejang, which is soaked in a soy brine for days. Yangnyeom gejang is mixed and eaten much sooner – usually the same day or within a couple of days – and it is famous for being so good with rice that Koreans call it a “rice thief” (bap doduk). This guide explains the sauce and how to make it with safety in mind.

Yangnyeom Gejang Sauce at a Glance

What it is

• A thick, sweet and spicy chili marinade for raw crab

Main ingredients

• Gochugaru, soy sauce, fish sauce, corn or rice syrup, garlic, ginger, green onion, sesame

Taste

• Sweet, spicy and savory with a sticky, glossy texture

Main uses

• Yangnyeom gejang (spicy crab), spicy marinated shrimp, spicy raw squid or octopus

What is Yangnyeom Gejang Sauce Made Of?

The base is plenty of gochugaru bloomed in soy sauce and aekjeot (fish sauce), then made sticky with syrup so it clings to every piece of crab. Typical styles include:

• Classic: gochugaru, soy sauce, fish sauce, syrup, garlic, ginger and green onion.
• Fruity: grated Asian pear or onion for a softer, rounder sweetness.
• Extra-hot: with sliced cheongyang chilies.
• Shrimp version (yangnyeom saeujang): the same sauce on peeled raw shrimp.

What Does Yangnyeom Gejang Taste Like?

The sauce hits sweet first, then spicy and deeply savory from the fish sauce. The raw crab meat is soft, almost jelly-like, and naturally sweet. Most people eat it by sucking the meat and sauce out of the shell and then mixing the leftover sauce with hot rice.

Easy Yangnyeom Gejang Recipe (Serves 2–3)

Safety first: this dish uses raw crab. Buy only very fresh or flash-frozen crab from a trusted seafood seller, keep it cold at all times, and eat it within 2 days. Raw shellfish is not recommended for pregnant people, young children, older adults or anyone with a weakened immune system.

Ingredients

• 2 blue crabs (about 1.3 lb / 600 g total), very fresh or frozen
• 1/2 onion, thinly sliced
• 1 green onion and 1 green chili, sliced

Yangnyeom Gejang Sauce

• 5 tbsp gochugaru
• 4 tbsp soy sauce
• 1 1/2 tbsp fish sauce
• 4 tbsp corn syrup or rice syrup
• 1 tbsp sugar
• 2 tbsp minced garlic and 1 tsp minced ginger
• 1 tbsp sesame seeds

Instructions

1. If frozen, thaw the crabs in the refrigerator. Scrub the shells with a brush under cold running water.
2. Remove the apron, lift off the top shell (keep it and the roe), pull out the gills and trim the leg tips and mouth parts with kitchen scissors.
3. Cut the body into 4 pieces. Lightly crack the large claws so the sauce can get in.
4. Mix all sauce ingredients and let them sit 10 minutes so the chili flakes swell.
5. Gently toss the crab, onion, green onion and chili in the sauce until well coated.
6. Cover and refrigerate for 2–3 hours (or overnight) before serving cold with hot rice. Eat within 2 days.

Tip: Freezing the crab for a few hours before cleaning makes it much easier and safer to handle and cut.
