In a small bowl combine sour cream and chives and season to taste with salt and pepper. On work surface lay out individual salmon slices, thinly spread with chive cream, spoon caviar onto each piece and spread carefully over length of slice. Roll up salmon starting with largest end to make a loosely-rolled rosette. It should stand up on one end. Be patient and have fun! Arrange on a platter and go crazy decorating with garnishes.
