Urgent! I just promised my neighbor that I would make an Easter cake with her two children tonight. She asked me if I would do it. I have traditionally made an Easter garden cake with tiny marzipan vegetables. I always used paste food coloring to prevent ruining the texture of the marzipan. I live in the woods right now and cannot get to a store that sells paste colors. When I looked through my decorating collection, I realized that I didn't bring my paste colors with me. All I have is liquid! Is it possible to convert the liquid to a paste? Is there some way to reduce it and add a thickening ingredient that would work?
