Thank you everyone for your input. It sounds like it could be just about anything resulting in the bad taste... The funny thing is, is that I didn't even notice this taste in my icing until like a few months ago.. maybe I've just gotten too picky idk. About the butter flavor reference, I only started using the butter flavor after I noticed the weird taste, so I'm pretty sure it's not that. But even so, I wouldn't mind getting some higher quality flavors anyways just for better tastes
Also I found that adding butter flavor actually made it taste better.. That and lemon juice, anyone ever try lemon juice?
carmijok, I would love to use all butter, in fact the one time I did use all butter in my icing was probably the most satisfied I have ever been with the outcome, but as I was piping my borders, it was melting due to the heat from my hands- and because of that, my shell borders didn't have that crisp sharp look, and of course I don't want the color to be too off white. Plus, I have to travel with the cakes in the back seat of my vehicle for 2 hours..in May.. in Nebraska.. It could either be scorching hot out or snowing lol! Sorry I'm just a little nervous about this being my 1st cake and all. Hoping I'm not in over my head, then to add this icing issue just makes it a little more stressful.
