In a food processor or mixer, combine butter, cream cheese, and white cheddar. Add garlic, green onion and ground pepper until well combined.
Using your hands, form a ball. Alternatively, place mixture onto the center of a 12" x 12" piece of saran wrap and pull each corner up tight to form a ball, then release.
Add pomegranate arils to a plate. Roll cheese ball to cover the surface. Add more seeds by hand to completely coat the ball.
Tightly cover in plastic wrap and refrigerate 30+ minutes until firm.
Ornament Garnish
Add Rolo to the top to create the stem and optional rosemary and bow. Serve with crackers and veggie slices.
Notes
Shred cheddar fresh for the best texture and flavor!
Serve at room temperature for the creamiest texture. It can be served immediately after chilling as well.
