If there is a single technique to level up home salmon, it’s broiling miso. The sugars in miso, mirin, and honey caramelize hotter, faster, and more evenly than brushed-on butter or oil, which often beads on the fish instead of sticking. The secret is to let the miso mixture sit on the fish long enough to season the flesh, then hit it with brutal direct heat so it lacquers and blister-browns just before the fish overcooks.
