Japanese roasted yellowtail collar (aka Hamachi collar) could be one of the easiest recipes I will post on this blog! However, it is one of the most delicious fish dishes you can make! Yellowtail collar is a delicious part of the yellowtail fish that is tender and fatty. When roasted with some salt, the fatty flesh is perfect dipped in soy sauce. For an even more fresh taste, add a squeeze of lemon! All you need to make this dish is yellowtail collar, salt, and an oven on broil setting. In just 10 minutes, you have an appetizer or healthy lunch dish that is often offered at Japanese restaurants!
