Unagi Kabayaki is a Japan-style fish preparation where the Unagi Eel is butterflied out, then repeatedly dipped into an umami rich sweet soy sauce before grilling over an open flame. This fish is an excellent source of Omega-3, vitamins and proteins, and is the perfect and scrumptious item even for beginners at home. Just thaw and reheat in a microwave, toaster, or toss the vacuum pack in a pot of boiling water for 5 minutes.
