- Melt butter in a large nonstick (12-inch) pan or stockpot over medium heat. Stir in shallots and ginger and cook until softened, about 4 minutes. Pour in sake, cook until liquid is reduced by half. Add water, miso and dashi granules; whisk until smooth. Stir in chicken broth, mushrooms and half of green onions. Bring to a simmer. Rinse any ice glaze from frozen Alaska Salmon portions under cold water. Turn off heat and gently add seafood to liquid, skin side down. Return heat to a simmer.
- Once simmering, cover pan and cook 4 to 5 minutes for frozen seafood or 2 minutes for fresh/thawed fish. Turn off heat and let seafood rest 5 minutes or until seafood is opaque throughout. Remove seafood to warm soup bowls.
- To serve, add 4 oz. udon noodles and one cup liquid to each bowl; garnish with reserved green onions and parsley.
