Chop smoked salmon into fine pieces. It doesn't have to be perfect - just do the best you can.
Mix together the smoked salmon, goats cheese, butter, and lemon juice.
Season with black pepper to taste. Line a container (that can be sealed) with parchment paper.
Scoop the mixture and form into ~1 inch balls. Place the balls into the parchment-lined container. Set in the fridge overnight (or at minimum a few hours) for the mixture to firm up.
