Melt 4 tablespoons of butter in a small heavy saucepan over medium heat. Add the garlic and heat, stirring, until fragrant. Add the capers and lemon juice and bring to a simmer. Stir in the remaining 4 tablespoons of butter one at a time, whisking to emulsify. Remove from heat, and add the lemon zest and parsley. Serve at once.
