Hi, so far the only cakes I've done have been one tiers. I want to make a two tier one for my sisters birthday, but am wondering how I do it? Do I completely cover the bottom layer with the icing and then stack the next cake on top? If so, what do I use to stick the tiers together? Buutercream? Apricot jam?
Oh and also while I'm here, how long does fondant icing last once the pack has been opened? I made my daughter a cake last week and have warpped the remaining icing and put in airtight containers, and am hoping to use this next week when I make my sisters, will it be OK?
Check out one of the many videos on YouTube on how to stack a cake. I know the visual works best for me. Basically you frost/decorate each tier then dowel the bottom tier and place the top tier (which is on a cake round) on top of the dowels. You don't need to stick them together, they stack, not stick. Tho you may find that the cake round may stick a tiny bit to the top of the bottom tier.
As for the fondant, you will probably need to warm it up in the microwave for a few seconds and knead it well to get it soft enough to work with next week.
