To make this cheese ball, start by shredding the white cheddar cheese and adding it to a food processor alongside the cream cheese, cranberries, pecans, chives, worcestershire sauce, and cayenne pepper.
Pulse and process the ingredients together until they're fully combined with some texture left. You will need to stop the food processor and use a spatula to scrape down the sides, in order to ensure that the ingredients are fully incorporated.
Once the cheese mixture has come together, transfer it to a large plate and use your hands to form it into a ball. I recommend spraying your hands lightly with oil, to ensure that the cheese doesn't stick to them.
Then, pour the pomegranate arils onto the plate and roll the cheese ball in the pomegranate arils, until it's completely covered in them. You might need to add some of the pomegranate arils to the cheese ball, by hand, in order to fill in some of the small gaps.
Once the cheese ball is fully coated in the pomegranate arils, wrap it tightly in plastic wrap and place the cheese ball in the fridge to chill. You can allow it to chill as little as a few minutes, or as long as overnight, depending on when you want to serve it.
When you're ready to serve the cheese ball, remove it from the fridge and carefully unwrap it. Top it with a sprig of fresh rosemary. Then, transfer it to a plate, serve with crackers, and enjoy!
