4. After cooking, add the cream and soy sauce and put in a blender until foamy. Set aside.

Presentation
Cut the leeks in half lengthwise, then cut into 5-6 cm (2") lengths. Allow 6-7 pieces per person. Line the leek pieces up on plates. Reheat the eggs and place one on each leek "raft," add the shrimps and spoon the foamy zucchini sauce over each egg. Serve warm.
