In a small bowl, combine 2 tablespoons well-softened butter with 1/2 teaspoon citrus zest, 1/8 teaspoon kosher salt, 1 1/2 teaspoons finely chopped fresh tender herbs (chives, mint, parsley, cilantro, basil), and 1 teaspoon honey or maple syrup (optional).
Mash with a wooden spoon until well-combined.
Store tightly covered in the fridge for up to 3 or 4 days.
