I am trying to make a Golf fondant cake with a water trap. Not sure how to make the water look like water. Can I use some kind of sugar water mixture?
There's been a lot of great cakes with various methods of water posted on CC. I've seen piping gel colored blue like this cake: http://www.cakecentral.com/cake-photo_1184994.html The color was spread over a prepared white or blue background. I've also seen people use buttercream or a combo of buttercream and piping gel like this cake: http://www.cakecentral.com/cake-photo_1563149.html In this example, several colors of blue and white were put in one bag and piped on. HTH!
I use piping gel and color it blue.
I used piping gel on this baby shower cake. It was white buttercream underneath piping gel tinted blue. You'll do great!
I coloured grapefruit jam for the water in a swimming pool cake, it tasted so much nicer than piping gell.
