Make Dipping Sauce:

In a small bowl whisk together all dipping sauce ingredients.

Make Filling:

Chop scallion and pick over crab meat to remove any bits of shell and cartilage. Break up larger pieces of crab.

In a dry small heavy skillet toast sesame seeds with salt to taste over moderate heat, stirring frequently, until golden, about 2 minutes. Transfer seeds to a medium bowl and cool slightly.

Add egg white and gingerroot to seeds and lightly beat.
