Step 1: Ensure your unsalted butter is completely softened to room temperature. This is crucial for a smooth and well-incorporated Vodka Butter. If it's too cold, it will be hard to mix; if melted, it will separate.
Step 2: In a medium mixing bowl, combine the softened butter, vodka, minced garlic, finely chopped fresh parsley, chives, thyme, lemon zest, sea salt, and black pepper.
Step 3: Using a spatula or a sturdy spoon, vigorously mix all the ingredients together until everything is thoroughly combined and the butter is uniformly flavored. Scrape down the sides of the bowl as needed.
Step 4: Lay out a piece of parchment paper or plastic wrap on a clean surface. Spoon the Vodka Butter mixture onto the paper, forming a rough log shape.
Step 5: Use the parchment paper to roll the butter into a tight log, about 1.5 to 2 inches in diameter. Twist the ends of the paper to seal the log securely, like a candy wrapper.
Step 6: Place the wrapped Vodka Butter log in the refrigerator for at least 2 hours, or until it is firm enough to slice. This chilling time allows the flavors to meld beautifully and makes it easy to portion.
Step 7: Once firm, unwrap the Vodka Butter and slice off rounds as needed. Store any remaining Vodka Butter in an airtight container in the refrigerator for up to 2 weeks, or freeze for up to 3 months for longer storage.
