I added a box of Sugar Free Pudding to my usual BC. I can't get the grainy feel out of it. Nothing that I have tried works. Any suggestions please?

In the future don't use sugar-free.
It *may* get better as it sits and the pudding has a chance to be absorbed.

I have never heard of adding pudding mix to bc. What does this do?

Has anyone ever added jello mix to buttercream? What happened?

That's what I did....sugar free......I had added pudding before with no trouble. The grocery store only had SF yesterday so now I know.

It's been sitting all night and it is still grainy. I'm afraid I must start over.

I have added jello before when trying to achieve red. I would suggest dissolving it in a very small amount of hot water before adding it though. You don't want the same problem that I'm having. =)
