Place soft boiled egg in a 1-pint mason jar or comparable sized container that your immersion blender fits snugly in.
Add the other ingredients and blend with an immersion blender until dressing is thick and creamy, about 30 seconds. If you don't have an immersion blender use a small food processor or blender.
Serve as a salad dressing, dipping sauce for artichokes, or drizzled over asparagus. I bet it would be delicious as a sauce for grilled or pan fried fish, or chicken.
