Place the cream cheese in a bowl and beat until lightened. Mix in the remaining ingredients, except walnuts. Spread the nuts on a plate. Lightly dampen your hands with cold water and shape the cheese mixture into a 2-inch round log. Coat the log with nuts, gently pressing them on to help them adhere. Wrap and refrigerate the cheese log at least 2 hours to firm up. Keep refrigerated until needed; can be made a day in advance of serving.
Note: To coarsely crush the walnuts, place them in a thick plastic bag and set on a cutting board. Use a kitchen hammer to crush the walnuts into smaller, but still visible pieces.
