Bring the chicken broth to a boil in a large pot. Season with salt, then add the pasta and cook until al dente according to the package directions. Drain well, return the pasta to the warm pot, cover, and set aside.

While the pasta cooks, prepare the seafood. Flake the canned salmon and remove any bones, thaw and roughly chop the shrimp if needed, and chop the imitation crab into bite-size pieces. Set aside.

In a separate large saucepan, melt the butter over medium heat. Whisk in the cornstarch until smooth, then gradually add the milk, stirring constantly to make a creamy base with no lumps.

Pour in the V8 juice and continue stirring until the sauce thickens slightly. Bring it to a gentle simmer, not a full boil.

Add the diced onion, minced garlic, and grated ginger. Season with black pepper, cumin, celery seeds, turmeric, cayenne pepper, and red pepper flakes to taste. Simmer for 5 to 7 minutes, until the onion softens and the flavors blend.

Stir the shrimp, imitation crab, and salmon into the sauce. Cook gently until the shrimp are heated through and the sauce is thick and creamy, about 3 to 5 minutes. Remove from the heat once the seafood is fully warmed.

Serve the seafood sauce over the warm pasta right away, or chill it for 3 to 4 hours for a cold seafood pasta salad. If serving cold, stir before serving and drain off any excess liquid if needed.

For a lower-carb option, serve the seafood mixture on its own as a creamy seafood bowl instead of over pasta.
