Using a microplane grater, remove the zest from both lemons and set aside. Juice both of the lemons into your immersion blender carafe or other preferred receptacle, such as a mason jar or deli container. Add half of the lemon zest into the carafe with the lemon juice.
Add the garlic, honey and dijon mustard to the lemon juice and blend. With the blender running, drizzle in olive oil slowly and blend. Stir in the chives. Season to taste with Kosher salt and black pepper.
You can also use a “bullet style” blender to make this dressing, but the dressing won’t stay emulsified for long. Adding the oil in a slow steady stream will ensure that the dressing stays emulsified for hours if not days.
