What I do is make them as the order comes in also. Usually it is more than one at a time, so what I do is make a batch in my kitchen aid mixer, it tends to get the fluffiest whip with the kitchen aid. But you have to have at least 24 oz in the bowl or it will not whip well. since the Whip atachment does not touch the bottom of the large bowl. I then remove what I need for one 8 oz put it into a pyrex measuring cup, then I add wiltons color with a toothpick, then add fragrance and whip again with a regular mixer. This works the best for me, I've tried premaking but it ends up deflating or getting to hard, I've tried only using a hand held mixer but it does not get as fluffy. If anyone has a better technique I'd love to hear, Everyone loves these but I really dislike making them this way.
