METHOD
1. Prepare the daikon. Slice the daikon into thin, even rounds or strips, suitable for placing each piece of salmon on top. Rinse the slices under cold water to enhance their crispness and freshness.
2. Assemble the dish. Lay out the daikon slices on a serving plate. Place one piece of seared salmon on top of each daikon slice.
3. Add the caviar. Spoon a small amount of caviar on top of each piece of salmon.
4. Garnish. Sprinkle finely sliced spring onions over the top.
5. Serve. Serve immediately as a refined appetizer or part of a larger meal.
