Prepare Broth Base: Add seafood stock, ginger slices, and crushed garlic to a pot. Bring to a gentle simmer over medium heat for 5 minutes, infusing rich flavors.

Season and Slice: Pat shrimp, squid rings, scallops, and fish fillet dry. Lightly season each with salt and pepper for balanced savory notes.

Steam Seafood: Arrange seafood in a shallow heatproof dish in a single layer. Steam over boiling water for 3–4 minutes, until just cooked and tender.

Soak Noodles: Meanwhile, soak rice noodles in warm water for 2 minutes or until pliable but still slightly firm to maintain authentic bite.

Combine and Warm: Divide softened noodles evenly among bowls, then ladle fragrant broth over each. Immediately top with steamed shrimp, squid, scallops, and fish.

Garnish and Serve: Finally, sprinkle vibrant scallions and cilantro leaves. Drizzle light soy sauce and sesame oil drops, then let sit 1 minute to meld aromas before serving hot.
