How to make a color flow edible image for a cake or cookie when you don't want to spend $8 on color flow mix.
Step 1 - Print out (or draw) the image you want to create. Tape wax paper over printed image.
Step 2 - Make thin consistency royal icing (okay you still have to spend money on meringue powder but this can be used for decorating cookies or in buttercream). According to Wilton, test the consistency of the icing by dropping a small amount of icing into the mixture. If it takesa full count of ten to disapper, it is the right consistency. If it disappers sooner, add stiffer icing to the mixture. If it takes longer than 10 seconds, add more water. Careful, add water a few drops at a time. A little water goes a LONG way.
Step 3 - Outline your image and let set. Next to outline, create a bunch of test dots about the size of a nickel. This will be your "image set indicator" to determine if your image is dry and ready to be transferred.
Step 4 - Fill in with icing.
Step 5 - Wait
Step 6 - Grab a Snickers, this is going to be a while (2-3 days)
Step 7 - Two to three days later, test dots to see if image is set. If dot doesn't smoosh when you press down, image is ready to be transferred to cookie or cake.
Step 8: To transfer, place the wax paper at the edge of your table. Pull the wax paper down toward the floor. The image will separate from the paper so put your hand out to catch it. If you miss, don't worry just go back to Step 1. No seriously, if you drop the image, it will shatter into a bunch of little pieces and you will have to start over again.
