用法筆記
This sense belongs to the cooking domain and has a different historical origin from the water-related senses. Only the objects of dredging are foods; it never refers to non-food items. 'Dredge' is more specific than 'sprinkle' because it implies coating the entire surface, not just scattering powder on top.
