Fondant is a form of icing that can be moulded and shaped into decorations that can be used to decorate cakes, cupcakes, cookies and other baked goodies. Anyone who has watched a cake decorating program on television will know there are a variety of items that can be created with fondant. One thing you can make is a fish, and you don't even need a fish cutter to make it. A leaf cutter and a few tools are all you need.
Begin by covering your hands with a dusting of cornstarch and knead your fondant until it becomes more pliable and easier to work with.
Sprinkle another dusting of cornstarch on your work surface and roll out your fondant with a rolling pin to approximately the same thickness as a CD.
Use your leaf cutter to cut out a leaf shape from the fondant. Just press the cutter into the fondant until you feel it reach your work surface.
Flip over the leaf shape so you have a smooth, clean surface to work with. Imagine that the more rounded end of your leaf cutout is the head and the pointed end is the back side of the fish.
Use your X-acto knife to cut a tail fin and a pectoral fin. At their simplest, both of these fins are just two triangular cutouts. However, you can also make these fins more ornate like the flowing fins on a betta fish, for example. The size of your fins will vary depending on the size of your leaf cutter.
Dip your brush in some water and apply it lightly to the areas where you will be applying the fins. The pectoral fin should be placed around the centre of the leaf cutout, and the tail fin will be connected to the back end of the fish, which is the pointed end of the leaf cutout.
Press the fins very lightly onto the leaf cutout where you have applied the water.
Use a toothpick to gently draw scales onto the fish's body. You only need to press hard enough for an indention, but not all the way through to the other side.
Use frosting or water to apply the fish to your baked goodies.
