Set out whole potato chips on tray making sure they are easy to pick up and stable on a flat surface.
Bring out salmon mouse from refrigerator and stir to a spreadable consistency. (If already in a bag, massage it a bit and put to the dispensing edge).
Put mousse in a pastry bag with tip or a food storage bag with a corner clipped for dispensing.
Repeat these steps for sour cream if you are using, but in a smaller bag.
Dispense mousse on top of potato chip in a small circle, staying in center and leaving enough edge so it does not slide off.
If using sour cream, apply a small dot in center of mousse.
Garnish with a small sprig of fresh dill leaf. (or other desired garnish).
