Canned Frosting

So there are times you run out of time, energy, etc. and you just use can frosting. I recently had one of those experiences. The chocolate never lets me down. Vanilla, on the other hand has this nasty taste. So I did a little experiment and bought three different brands. They all have the same plastic taste. Its like there is something just off in the frosting. I can not put my finger on it, but it just doesn't taste right. From this point on I will probably make my own frosting. I wish I could put my finger on the funky taste. I know its a time saver, but at what cost. I would rather take the time to make it than to server something that leaves a bad after taste in a mouth.
