🌐 General Information
Bajirak (바지락), known in English as the short‑neck clam or Manila clam, is one of the most widely used shellfish in Korean home cooking. These small, oval‑shaped clams are appreciated for their tender bite, clean brininess, and ability to create a naturally savory broth with almost no effort.

🛒 Shopping & Selection
Manila clams are widely available in East and Southeast Asian markets, Korean grocery stores, and many large mainstream supermarkets. Their popularity and long shelf life make them one of the easiest shellfish to source.
What to Look For (Live Clams)
- Closed shells or shells that snap shut when tapped
- Fresh ocean scent—never sour, fishy, or ammonia‑like
- Moist, intact shells without cracks or dryness
- Active response when handled (a sign of life and freshness)
Frozen Clams
- Packaging should be fully sealed
- No off‑odors when opened
- Minimal ice crystals, which indicate proper freezing and storage
Frozen clams are convenient for soups and stews, though they won’t have the same plumpness as fresh.

🧊 Storage
Short‑Term Storage (Live, In Shell)
- Keep clams in the refrigerator in an open container (bowl or colander)
- Cover with a damp towel to maintain humidity
- Do NOT store in water or directly on ice—this suffocates the clams
- Use within 2–3 days (up to 4 days at most)
Purging Before Storage
To remove sand and grit:
- Place clams in a shallow container of lightly salted water
- Soak for 1–2 hours (or overnight for heavily sandy clams)
- Drain and store as above
Long‑Term Storage (Frozen)
Shucked Meat
- Remove meat from shells and clean thoroughly
- Store in airtight or vacuum‑sealed bags
- Freeze for up to 3 months for best quality
Frozen in Shell
- Live clams can be frozen in moisture‑vapor‑resistant bags
- Texture becomes slightly softer after thawing
- Still excellent for soups, jjigae, and stir‑fries

🔪 Common Preparation
- Purging: Soak in salted water to remove sand
- Cleaning: Rinse under cold running water
- Shucking: Open the shell and remove the meat for soups, stir‑fries, or slicing
- Trimming: Some cooks remove the dark stomach contents for a cleaner flavor
Bajirak cook very quickly. Overcooking makes them tough, so most dishes rely on brief boiling, steaming, or flash‑cooking. When the shells open, they’re done.

📜 Historical & Cultural Notes
Bajirak have long been tied to Korea’s coastal communities, where tidal flats provided an accessible source of protein for families with limited means. Clam gathering was often a communal activity—children and adults alike combing the sand during low tide.
In Korean cooking, bajirak are valued not only as an ingredient but as a broth‑maker. A handful of clams can transform plain water into a clean, savory stock, which is why they appear so frequently in everyday soups and noodle dishes. Their role in dishes like kalguksu reflects Korea’s broader tradition of building flavor from simple, natural ingredients.
