When can we let baby try solids?

My daughter is 2.5 months old and all we ever give her is breastmilk or formula as a supplement. I know they say to introduce solids at 6 months, but as far as letting her taste them, should that be 6 months too? I've wanted to have her try a bit of frosting or Cannoli filling just to see if she likes it, but haven't since I don't want her getting sick.
