I am working with IMBC for the first time and was wondering if in place of egg whites and wasting the egg yolks, could I just use 100% liquid egg white?
Also, will fondant attach to IMBC like buttercream icing?
Lastly, could I color IMBC the same way as buttercream icing?
I use most SMBC and always used pasturized egg whites in the box. It works well with my recipe.
It depends on how heavy the pieces are. Last night I made a small cake covered with SMBC and placed two large bumble bees on top and a bunch of medium daisies. I have daisies on the sides and I have letter cutout on the side too. I just like press them in a little. The cake was in the refrigerator over night; now I have it in my office and the pieces are still on the cake. Nothing's moving. Now I have had gumpaste bows slid of the cake after I airbrush the buttercream
Now with colouring; the buttercream has a slight yellow colour so you may not get true colours because of the yellow undertone. I have heard that candy colours are best to use if you want real vivid colours. Just remember there is the yellow undertone.
Hope this helps.
Ooops! I did not directly answer the colouring question: Yes, you can colour the IMBC in the same way you colour other buttercreams.
The 100% egg whites are perfect, but some brands I heard may give problems. I have tried three brands so far and never had a problem.
