I want to make an open box heart cake with flowers in the middle but I don't know how to secure the top part of the box so that it won't fall or crush the gumpaste roases. Any ideas?
For the lid you can use styrofoam cut into the shape you want or use rice krispie treats molded into the pan of your heart - covered in fondant. Pour chocolate or put buttercream on the lid of the RKT then your fondant - so it's nice and even
You can prop up your lid with a dowel in the middle of your heart cake
You have a few options depending on what you want to make the lid out of. I've done three different ones that you can see in my photos.
In this one ( http://cakecentral.com/gallery/1924472 ) I made the cover of the basket out of pastillage (essentially it is a harder version of gumpaste) and propped it up with skewers. Soda straws would work as an alternative for this method because the pastillage does not weigh much. I covered mine with buttercream, but you could use fondant just as easily or even use straight gumpaste.
In this one ( http://cakecentral.com/gallery/1923365 ) I made the cover out of foamcore and covered it in fondant. I held it in place with a bamboo skewer which I hid with a bow on the center of the cover.
In this one ( http://cakecentral.com/gallery/1923349 ) I used a sugar cookie baked in the same shape as the box, put a thin layer of cake on it and covered the whole thing with fondant. The weight of the whole cover held it in place on the side, but if I wanted to put it on the box I would have used just the cookie (less weight) and held it up with soda straws or skewers. You could hide a straw or two among your flowers and use a third one to anchor the back of the cover in place and hide it with a small decoration. HTH
Thank You both! It was really helpful!
