I cheated and added a little more salmon. Wonderful and simple
Made for a holiday brunch buffet (lox is soooo expensive so wanted a way to extend it.) Trick is to blend the room temperature cream cheese first before adding the sour cream etc This gets out all the lumps (I used my KitchenAid mixer.) Be sure to dice lox up in smallish pieces - I separated it into strips first so as to make it go farther. Decorate with some bits of lox and diced green onion. Pretty!
Have served it twice now, big hit; certainly needed to soften the cheese more prior to blending.
