Let the butter come to room temperature. To speed this up, cut the butter into small cubes and place in a small bowl.
9 oz butter
Finely chop the herbs (dill, chives, and parsley) - the finer you chop them, the easier they'll blend into the butter. Zest the lemon and crush the garlic. Add all ingredients to the softened butter, season with salt, and mix with a wooden spoon until completely combined.
