I opened up a fresh bucket of satin ice black fondant the other day to cover a cake & this is how it looked once I covered it...
Why was there so many holes/cracks? Usually when I put it on, it's smooth, not rough looking like that. Maybe I didn't knead it enough?
Well, I can't see a picture, but I'll do the best I can to help!
I use Satin Ice all the time. On occasion, I've had my fondant look like you're describing. It could either be that it wasn't kneaded long enough, or it was kneaded too long. I've had it happen when I color white Satin Ice and I've had to keep adjusting the color and kneading it a lot. How long did you knead it for before putting it on the cake? That might give me a better idea of what might have happened.
How did you roll it out?
I used a marble rolling pin to roll it out. I don't think I kneaded it enough because the next cake I covered with black fondant came out better than this one.
I agree, it was either too much or too little kneading. Satin Ice is a good quality fondant and should not have problems you have described!
