Bring a pot of water to a gentle boil, and carefully lower eggs into the water (I use a slotted spoon), and cook for 6-7 minutes. Then, transfer the eggs to an ice bath to stop the cooking process and make peeling easier. When peeling, always peel while running under cold water and you will have beautiful eggs! Allow to cool before adding to the salad.
Prepare the dressing:
Whisk together the ingredients for the dressing until emulsified—refrigerate until serving.
Make the salad:
Arrange the lettuce on a large platter or place in a large salad bowl. Top with chopped radicchio, soft cooked eggs (cut in half), cherry tomatoes, cooked corn, radishes, cucumber, and carrots.
