1. Preheat oven to 250 degrees Fahrenheit.
2. Combine garlic and oil in a small, oven-safe dish (such as a ramekin). Cover and cook for two hours. Let cool, then transfer garlic to a blender (reserving the oil). Add lemon juice, lemon zest, and honey and blend until smooth. Slowly add reserved oil while blending, until a thickened dressing forms. Season with salt and pepper to taste. Whisk in the chives.
