How to Make It
In a small skillet, heat the butter. Add in the panko and cook, stirring, until golden and crisp, 1 minute. Stir in the nori. Transfer to a plate to cool.
In a small bowl, combine the shiso leaves with the white miso and mash to a paste. Adjust the consistency with water until spreadable.
Season the scallops with seaweed salt and transfer to two plates. Garnish with the ginger and nori breadcrumbs and dollop with the shiso miso. Serve immediately.
