When you get over to One Perfect Bite, just search out the January 16, 2010 post of the recipe. You'll find the archive on the right. I'm really doing you a favor by not knowing how to link directly to the recipe (I tried). You'll find many entries to explore.
The only "tweak" to the recipe came when I wanted pink icing and had no food coloring. I used about a drop and a half (sorry, can't relate that any better) of beet juice. You absolutely cannot taste beets!!!!!
HAPPY VALENTINE'S DAY TO ALL!
