In order to toast the nori, which is a step you can skip if it feels overwhelming, either use tongs to run it over the flames of your stovetop or put it in a hot sauté pan until it starts to blister, flipping as necessary. Toasted nori deepens the flavor and makes it easier to crumble by hand. Alternatively, you can use kitchen shears to cut the nori into small, dime-size pieces. My tip for peeling ginger is to use a spoon with the cupped side facing down; it removes less of the flesh than a typical vegetable peeler and is able to reach the nooks much easier. Bonus: It keeps the juice from splashing in your face.
