Can you pipe RI on BC icing? I know you can do RI on Fondant, but was curious if it would work on BC...I know the oils would not allow it to harden, but not sure that would matter so much...has anyone ever tried this?
Thanks...

IDK, never tried it. Iâm not sure why you would want to when you can make ur BC stiff enough.

No real reason...just seen it done on cakes covered in Fondant, but I get my BC smooth like that, and liked how those look...etc. RI is smoother to write with than BC...wasjust a thought...any other input?

Yes RI *can* be piped on B'cream.
