In a medium bowl, combine the softened butter, olive oil, lemon juice, and red wine vinegar until smooth.
Add the minced garlic, lemon zest, The Holly Tree Organic Parsley Leaves, Organic Oregano Leaves, Organic Chili Flakes, Organic Black Pepper Powder, and Organic White Pepper Powder.
Mix thoroughly until all the herbs and spices are evenly incorporated into the butter.
Fold in the chopped fresh parsley, if using, for added color and texture.
Spoon the butter onto a sheet of parchment paper or plastic wrap and roll it into a log. Twist the ends tightly.
Refrigerate for 1–2 hours, or until firm.
Slice into rounds just before serving, or allow it to soften slightly for use as a spread.
