Pat 4 oz lox dry with paper towel, then chop into pieces smaller than ¼ inch. Finely mince 2 tablespoon red onion and chop 1 tablespoon drained capers. Chop 2 tablespoon fresh dill.
4 oz lox, 2 tbsp red onion, 1 tbsp capers, 2 tbsp fresh dill
In a mixing bowl, stir softened cream cheese with a spoon until smooth and creamy. If too thick, fold in 1-2 tablespoon cream or sour cream to loosen.
